CFTP - Compression add-on for File Transfer Protocol
CFTP uses gzip and tar compression to reduce the size of the transferred files and combine them into one tar.gz archive, temporarily stored in the server and client tmp directories (useful for a large number of photos, text files and other small files in large quantities) and its auto-extracting on server, which significantly increases the speed of file transfer via ftp
The size of the tmp directory in the current version depends on the size of the transferred files, and the archive file is deleted immediately after the file transfer / receive operations are completed.
