Mostly speed: small files go four times faster over SFTP and twice as fast over FTP, a 50,000-file folder on a distant server is on screen in 2.4 seconds, and 70,000 files reach your PC at an even pace. Plus permissions for FTP and SFTP servers, and This PC laid out as File Explorer has it.
FileZilla is safe and signed, but its main installer carries an offer Defender flags, and Google's top result led to a file Defender detects as a trojan.
Same server, same files, default settings. We timed WinSCP 6.7 and FileZilla 3.71.1, cut the connection mid-upload and checked where each keeps passwords.
We compressed source code, the Silesia set, JSON, photos and video 150 times with zip, 7z, RAR, zstd and xz. 7z made the smallest archives of code and text, zstd the fastest, and Windows' own zip took minutes.
Sharing grows a home of its own: short ftpie.link links with a password if you want one, one link for a whole set of files, screenshots and notes shared as themselves, and email with nothing to set up. Plus videos that play smoothly, with a playlist, and a long list of FTP fixes.
