Synchronization excluding folders/subfolders

Hello,

I want to exclude some dirs from synchronization so I put this in the mask:
which are the folders names.

But I see the program scanning through these folders and their subfolders which takes a long time. Is there something wrong with my exclusions or is this normal that he scans all dirs Everytime? Tnx and regards, fusi.

The site/cache/; site/sessions/ won't work.
Depending on your preferences, use one of these:
The last one works, if the path is relative to the root of the synchronization.
See https://winscp.net/eng/docs/file_mask#path

If none of this helps, please post session log file.

Tnx! It works!
