Before extracting, verify the integrity of the file. Always compare the file’s checksum (MD5 or SHA-512) against the hash provided on the official download page. This ensures the file has not been tampered with by third-party sites.
Always verify official sources. The portable version is distributed by the FileZilla project, not third-party "portable app" sites (which may bundle malware).
Obtain the package from a trusted source like PortableApps.com or the official FileZilla Project page under "additional options".
