Many admins combine SSH/SFTP + zip command:
sftp user@server
> get somefile.zip # already zipped remotely
Or automate zipping on server before SFTP transfer:
zip -r /home/user/data.zip /home/user/data/
Then download data.zip via FTP/SFTP.

Does anyone know an FTP server that transparently zips files/folders during download without pre-zipping? zip net ftp server
So far, no pure FTP server does this (FTP protocol lacks server-side pre-processing hooks).
Best workaround: Use HTTP (HFS, Nginx with gzip static) or SFTP + pre-zipped content.
FTP (File Transfer Protocol): A standard network protocol used to transfer files between a client and a server. It operates on a client-server model, typically using port 21 for commands and port 20 for data. Many admins combine SSH/SFTP + zip command: sftp
Compression (.zip): Since FTP is designed for transferring arbitrary files, combining multiple files into a single .zip archive is common practice to reduce transfer time and bandwidth usage.
.NET Integration: Many modern server-side applications use ".NET" libraries (like those from Xceed or Rebex) to programmatically compress files and upload them to a remote server in one automated workflow.
