How to use cm_copy to update the backuped files/dirs' comments

[Tangent Lin]

Problem i met :
1. I embeded the FastCopy.exe V3.54 into Total Commander with [em_fastcopyCopyTo] used %P%S and %T options.
2. I like to use the Ctrl+Z to add comments for the files/dirs in descript.ion.
3. FastCopy is very fast in my backuping files/dirs operation but it can not deal with the files/dirs' comments.
After the fastcopy's backuped operation , I have to use the F5(copy) operation with "Ovewrite all older" option to updat the comments.
4. I have found the commande line options of fastcopy.exe include the "/postproc=action_name" , but can anyone tell me how to use cm_copy to update the backuped files/dirs' comments automatically ?

Or is there another better way i don't know ?
