:D was just searching the forum to see if there was a way to do this.
OK, added to TODO list :-)
First I would like to thank you for creating this software, I absolutely love WinSCP, been using it for several years.
In the permissions dialog,
Checkbox as is: Set group, owner and permissions recursively
Add radio button options:
Apply to all files and directories
or
Apply to files only
or
Apply to directories only.
It's very rare that you want to chmod all directories and files to the same permissions.
I hope you will consider this suggestion.
Thank You
James
