I know the following filter :
name match *.(h|hpp|c|cpp|ini)
If I want to skip all files in the subfolder named "X"
I try to add
and name mismatch X
However, it doesn't work.
Can someone help me ? thank you very much.
Have a look at this thread: How to filter items by location or sub-folder
(I just moved it into the FAQs area. It wasn't there when you asked originally, don't worry. 
)
Yes, it works. Thank you.
Best Regards.
