How to synchronize only one file extension and exclude all other files

[fc622000]

Hi everyone,
I need to synchronize between two folders only files with the *.lnk extension.
To speed up processing, I would like to exclude all other files.
Is this possible? How should I configure the filters?
Thank you very much for your help.

You should not exclude all other files, but rather include only .lnk files.
Replace the default Include filter * (=everything) by *.lnk (=all .lnk files)
