History

Origins and early development

FileZilla originated in February 2001 as a class project undertaken by Tim Kosse and two classmates during their studies at in . The assignment initially called for a simple program, but they opted instead for a more ambitious FTP client to create a reliable tool for file transfers over FTP protocols. Written in C++, the project emphasized core functionality such as server connections, directory listings, and file uploads/downloads, marking the beginning of what would become a widely used open-source application. Early development prioritized a Windows-based using Microsoft's MFC library, reflecting the platform's dominance at the time. Although cross-platform compatibility was a long-term goal, the initial versions were Windows-specific, focusing on stability and ease of use to distinguish it from existing FTP clients. Kosse, in his final year of studies, continued refining the software post-assignment for personal use and broader improvement, laying the groundwork for its public availability. The project transitioned to open-source distribution under the GNU General Public License shortly after inception, as commercial prospects seemed unlikely, enabling community involvement from the start. The first alpha release occurred on February 27, 2001, via .net, followed by a beta in April and version 1.0 in June of the same year. These early releases garnered initial downloads and prompted rapid iterations, with updates incorporating user feedback on usability and reliability from early adopters. Over time, efforts to enhance cross-platform support led to the adoption of the library for the , though this major rewrite came later, solidifying FileZilla's accessibility across operating systems. This foundational phase established the project's commitment to , , evolving from a endeavor into distinct client and server products.

Key milestones and licensing changes

In November 2003, FileZilla was recognized as SourceForge's Project of the Month, which significantly increased its visibility, leading to over 4,000 daily downloads and enhanced community contributions including bug reports, feature requests, and volunteer translators. FileZilla Server was released in 2001 as a companion to the client, providing FTP and FTPS hosting capabilities with features like user management and directory permissions. Since its early development, FileZilla Client has been distributed under the GNU General Public License version 2 or any later version, emphasizing copyleft principles to ensure derivative works remain open source; FileZilla Server initially followed the same GPL-2.0-or-later terms before transitioning to the GNU Affero General Public License version 3 or later with the 1.x series in 2021. FileZilla Pro, a edition extending the open-source client with support for cloud protocols like , , and , was introduced in 2017 to offer enterprise-grade integration without altering the core GPL-licensed codebase. The FileZilla Client achieved a major milestone with the 3.0 series release on September 8, 2007, following betas in 2006; this rewrite introduced cross-platform compatibility using , directory filtering, and improved handling, marking a shift from the Windows-only 2.x branch. FileZilla Server entered its modern 1.x era in 2021 with version 1.0.0, and on August 28, 2025, version 1.11.0 was released, incorporating wildcard pattern support (using * and ?) for commands like , NLST, MLSD, and to enable flexible file querying, alongside options for write-only mount points and credentialed paths. In 2019, FileZilla participated in the European Union's Auditing (EU-FOSSA 2) , resulting in the identification and remediation of 10 vulnerabilities through community-submitted reports, reinforcing the project's commitment to robust auditing.

These updates ensure compatibility and reliability for professional cloud workflows.

Features

Transfer protocols and interface

FileZilla Client supports the File Transfer Protocol (FTP) for basic file transfers between local and remote systems, FTP over SSL/TLS (FTPS) in both explicit and implicit modes for encrypted connections, and the SSH File Transfer Protocol (SFTP) for secure transfers over SSH. These protocols enable compatibility with a wide range of servers, with FTPS explicit mode initiating encryption after a standard FTP connection on port 21 via the AUTH TLS command, while implicit mode assumes encryption from the outset on port 990. The FileZilla Pro version extends this support to include protocols such as WebDAV, Amazon S3, and other cloud storage services. Recent updates as of November 2025 include support for AWS IAM Identity Center and Google Cloud Service authentication for enhanced cloud integration. The user interface of FileZilla Client features a tabbed that allows simultaneous management of multiple server connections, facilitating efficient switching between sites without closing sessions. Drag-and-drop functionality simplifies file operations by enabling users to move files directly between local and remote directories or within the interface panes. Transfer queues organize pending uploads and downloads, supporting up to 10 parallel connections to optimize throughput while respecting server limitations. FileZilla handles interrupted s by resuming downloads and uploads from the point of disconnection, ensuring for large operations. It supports files larger than 4 GB through , which preserves file contents without ASCII conversion artifacts. Users can impose speed limits on individual s or globally to manage bandwidth allocation and prevent network overload. Remote directory listings are fetched and cached to reduce server queries and improve responsiveness during navigation, with options to refresh or disable caching for real-time updates. Synchronized browsing mirrors the directory structure between local and remote panes, automatically aligning selections to streamline comparative tasks like backups or mirroring.

Site management and automation

FileZilla's Site Manager provides a centralized interface for organizing and storing connection details to remote servers, enabling users to save configurations without re-entering information for each session. This tool stores data in an XML-based format, including server hostnames, port numbers (such as non-standard ports for specific protocols), and transfer modes like active or passive FTP. Credentials are supported through various logon types, including normal authentication with username and password, anonymous access, interactive prompts, account-based logins, and key file authentication for connections. Additional settings encompass default local and remote directories, time offsets for server synchronization, and protocol-specific options like encryption levels. Bookmarking in FileZilla enhances accessibility to frequently used sites by allowing users to create shortcuts from Site Manager entries, which populate a quick-connect dropdown for rapid connections. These bookmarks can be organized into folders, renamed, duplicated, or searched within the Site Manager, facilitating efficient management of multiple servers. and functionality supports transferring bookmark configurations as XML files, useful for migrating settings across installations or sharing with team members. Automation features in FileZilla streamline repetitive tasks, particularly through the client's directory comparison and management tools. The directory comparison function highlights differences between local and remote directories based on , modification time, or content, aiding operations by identifying files for , , or mirroring. Users can enable synchronized browsing to maintain parallel navigation between local and remote sides, ensuring transfers align with directory structures. For batch operations, the transfer persists across sessions via a database, allowing interrupted lists to resume without loss. queuing lets users assign higher importance to specific transfers, while built-in error retry logic automatically attempts failed operations up to a configurable number of times before moving them to a failed list for manual requeuing. On the server side, event captures detailed interactions for monitoring and scripting. Logs record events, commands, responses, and errors with timestamps, process IDs, and message types, stored either in the admin interface or as rotating files for long-term analysis. This supports external scripted responses by providing parseable output for custom , such as triggering alerts or actions based on detected events like failed logins.

Security and configuration options

FileZilla provides robust encryption options to secure file transfers, supporting (FTP over TLS) for explicit encryption on port 21 and implicit encryption on port 990, as well as (SSH File Transfer Protocol) on port 22. These protocols encrypt both commands and data, protecting against interception, with leveraging TLS certificates for and using SSH keys. Certificate validation in connections can be configured to use the system's trust store, ensuring verification against trusted certificate authorities before establishing a secure session. Additionally, since version 3.26.0 released in 2017, the FileZilla Client includes a master password feature that encrypts stored site manager data, including usernames and passwords, preventing unauthorized access to saved credentials. Configuration options emphasize secure and flexible network integration. The client and server support passive mode, which is firewall-friendly as it requires only outbound connections from the client, minimizing the need for inbound port openings on restrictive networks. In FileZilla Server, administrators can implement filters to allow or deny connections based on specific addresses or ranges, enhancing . For the Pro version, users can bypass proxy servers for specific protocols like or via the Site Manager's Advanced tab, allowing direct connections when proxies are unnecessary or incompatible. Logging capabilities support auditing with detailed, timestamped records of transfers and . In the client, logs can be enabled under > Settings > , including timestamps and export to files for review of transfer details like file paths, sizes, and errors. The server offers similar logging in its admin interface, with options to export logs and tools to monitor active sessions, including IP bans via autoban after failed logins or manual intervention. FileZilla incorporates mechanisms for maintaining through updates. The client performs automatic checks for new versions, which include patches, configurable under Edit > Settings > Updates. In 2025, FileZilla Server underwent a second independent audit funded by the , identifying and resolving issues such as crashes in TLS loading and handling, with the updated findings report confirming mitigations for improved stability in encrypted sessions. While legacy plain-text FTP remains available for compatibility, it is strongly discouraged due to its lack of .

This ongoing engagement, combined with its open-source foundation, has sustained its popularity since the early , supporting diverse use cases from personal backups to enterprise deployments.

Security and adware controversies

FileZilla has faced significant criticism for bundling third-party in its installers since 2013, when the project opted into SourceForge's DevShare revenue-sharing program. This arrangement wrapped the with offers for additional software, including , which antivirus tools like AVG flagged as potentially unwanted programs (PUPs). Users reported unwanted installations of toolbars, extensions, and search modifiers, leading to widespread outrage and antivirus detections. To mitigate risks, the FileZilla team recommended downloading from the official website rather than third-party mirrors, where an unbundled installer option has been available. Reports of bundled offers persisted into 2025, with users noting prompts during installation but expressing concerns over deceptive interfaces that could lead to accidental acceptance. Prior to version 3.26.0 released in June 2017, FileZilla Client stored FTP passwords in within XML configuration files such as sitemanager.xml and recentservers.xml, exposing them to risks from , disk access, or unauthorized file reading. This practice drew complaints for lacking basic protection, as anyone with access to the files could retrieve credentials without . In response, version 3.26.0 introduced encrypted storage protected by an optional master password, updating credentials in the transfer queue upon changes and requiring libfilezilla 0.9.2 or later. This shift addressed vulnerabilities to credential theft but required users to enable the feature manually. The project has also encountered security vulnerabilities identified through external audits. In 2019, FileZilla participated in the European Union's 2 bug bounty program via , resulting in the discovery and patching of seven vulnerabilities, including issues with file name escaping and other input handling flaws in version 3.43.0. More recently, a May 2025 security audit funded by the (OTF) for FileZilla Server examined new features for user and data protection. The audit resolved a medium-severity denial-of-service () vulnerability (V-001) involving crashes from parallel authentication requests in authorizator.cpp, fixed in version 1.10.3 by improving session handling to prevent exploitation by unauthenticated attackers. However, it noted ongoing concerns, such as cleartext storage of PINs and a low-severity issue (V-002) with limited review capabilities for shared access tokens, alongside effective but not exhaustive input validation in the web UI. Developer Tim Kosse, FileZilla's lead maintainer, has defended the bundling as a necessary revenue source for the open-source project's sustainability, emphasizing that offers are opt-in, disclosed upfront, and controlled by partnerships like since 2016. He clarified that no is installed without consent and suggested alternatives like portable binaries to avoid installers entirely. Despite these explanations, critics argue the practice undermines trust in the software, particularly for -conscious users.

Technical Details

FileZilla Client and Server provide cross-platform support primarily for operating systems, with official binaries tailored to specific versions and architectures. On , both the client and server officially support 64-bit editions of and , with 64-bit architectures preferred for optimal performance. The client also offers 32-bit builds compatible with and 10. While official ARM64 support for Windows is not yet available, community-compiled builds exist for recent versions, and efforts are underway to add native . For macOS, the client and server require version 10.13 (High Sierra) or later, with dedicated builds for both (x86_64) and (ARM64) processors to ensure native performance on modern hardware. Distributions are notarized to comply with Apple's security guidelines, preventing warnings, and the edition includes configurable directory access permissions to align with sandboxing best practices for file handling. On Linux, the client is distributed via universal formats like and for broad compatibility across distributions, with official binaries built against 10 (Buster) and compatible with later releases such as and . Installation typically requires the wxGTK for rendering the graphical user interface. The server features community-maintained ports optimized for and , with binaries built for 11 (Bullseye), though compilation from source is recommended for other distributions to meet dependencies. The cross-platform architecture relies on the toolkit, which delivers a consistent and behavior across Windows, macOS, and without platform-specific divergences in core functionality. Official support does not extend to mobile platforms like or , nor to embedded systems such as those in devices. Support for legacy operating systems ended progressively: and derivatives were dropped starting with version 3.8.1 in 2014 due to and constraints, followed by de facto discontinuation of as minimum requirements shifted to newer APIs. As of November 2025, releases such as client version 3.69.5 and server version 1.11.1 are optimized for contemporary environments, including enhanced stability on and full with (version 14).

Known limitations and bugs

FileZilla Client exhibits a persistent limitation in handling resume operations for large file transfers from IIS servers, often resulting in due to incompatibilities in the FTP resume . This issue remains unfixed as of 3.69.5. The transfer queue in the Client can experience crashes during high-load scenarios involving numerous simultaneous file operations, particularly when processing thousands of uploads. FileZilla Server lacks native full support for in its administrative , restricting configuration and monitoring to IPv4 environments despite partial protocol compatibility. Additionally, it does not include built-in clustering capabilities for , necessitating external load balancers or redundant setups for enterprise-scale deployments. Across both Client and Server, no native dark mode implementation exists; the relies on the host operating system's settings for any dark appearance, which may not fully adapt all elements. On distributions, occasional UI freezes occur, attributed to wxWidgets rendering issues during intensive operations like directory listings or transfers. For the IIS resume issue, users are advised to employ alternative FTP clients such as that better handle IIS-specific behaviors. Regarding Server vulnerabilities, including a 2025-identified condition from parallel requests leading to crashes, manual service restarts serve as a temporary until applying patches. Security-related crashes, such as those from malformed requests, are detailed further in the security controversies section. Bugs and limitations are primarily tracked through the official bug tracker, with 2025 releases incorporating fixes for reported issues, including improvements in stability and resource handling.
