Disable Compression (MODE Z)

Hi...
Is it possible to disable compression (MODE Z) in the ftp client for certain parts?
I like mode z for directory listing compression but not all the time for downloading compression.
When downloading allready compressed files like .rar files I get a higher download ratio when I turn OFF compression mode z.
(tested with flashfxp)
Greetz!

Unfortunately you can currently only turn it on/off completely, not partially. I will consider your suggestion for a later version.

Great...
A quick solution could be by making the ModeZ= setting in wcx_ftp.ini site specific?

If you're downloading data allready compressed with for example rar I quess the data cant be compressed much more so on-the-fly compression works as a disadvantage?

Perhaps the following helps:
wcx_ftp.ini, [General]
ZlibRatioBin=3 0..9:
zip library compression ratio for uploads. 0=none, 1=fastest, 9=strongest
ZlibRatioTxt=3 0..9: same as zlibratiobin, but for text files. You may want to set a higher value here, because text files usually compress better. Attention: The Cisco PIX firewall dislikes strength 1, and aborts the upload
Try setting ZlibRatioBin to 0. This way, only text files will be compressed, including directories.

Thanx for the tips!
