The following picture might illustrate what is meant. In addition to that question: If it is possible - any suggestion how to set up the config and/or appropriate command line? Simply applying compression for any data, including directory list (response for LIST/NLST) as well as usual data (response for RETR), is simply realized with: CMAP="gzip:FTOCL:ftp-data" If you have FTP-DeleGate proxy at client side, the compressed data will be decompressed with: CMAP="gunzip:FTOCL:ftp-data". If you don't have DeleGate at client side, it depends on what feature can be expected at client side. For example, if a client supports FTPS (FTP over SSL), it can be used because SSL includes compression of transferred data. | ....:''''''''''''''..... | ..:'' ''''':... | .'
