Extension allows to compress the transferred files. This reduces the network traffic and decreases the amount of time required to transfer files. Extension uses ZIP compatible compression method so you can restore files by any ZIP decompression program, such as WinZip, PKWare pkzip etc.

Also extension supports JAR, TAR, GZ and CAB compression types. You can choose the appropriate type in the Advanced settings window.

If it is used together with File encryption extension it allows to password-encrypt the transmitted files. This makes a transfer of files on networks considerably safer.
