exclude in keepuptodate

Hi,

I have:

keepuptodate -delete -filemask="|*.loc;*.pst;thumbnails/" K:\FirefoxProfile /media/USBHDD1/shares/FirefoxProfile

To exclude the folder 'thumbnails' but it does not. The filemask correctly ignores the *.loc &
*.pst files.

Can you please tell me the correct syntax?

I have sorted it thanks you.

However, I have another related question:

To what level of sub-directories does keepuptodate work in added/deleted files & directories?

Any level.
