value for the compression percent for files in the details dlg...
the formula (from FileDetailDialogInfo.cpp, line 287)
uTransferred!=0 ? (uCompression * 100.0 / uTransferred) : 0.0
but afaik compressed data isn't counted at part of the transferred data.
i've check and it seems this is the right formula
(uTransferred+uCompression) ? (uCompression * 100.0 / (uTransferred+uCompression)) : 0.0
i've also checked with a file which received corrupted data
and the values seem fine...
is this the right formula? or is there another one?
