Is it possible to exclude a folder with a same or similar name ?
Example :
I want to remove all folders that has a name backup
Sample Folder Name : Backup1,Backup2,Backup3
And i'd like to Remove all those backup using or calling the Backup folder name only ?
is it that possible?

Again, see https://winscp.net/eng/docs/file_mask
