Florence,

No, VFP is going to throw some rather strange errors if you try to work in a hidden folder. You can also have odd problems if your temp directory gets marked as hidden and/or system.

> I share my data folder as a hidden folder for eg : data$. When i try to do indexing use my application, it prompt error, but when i not make the files hidden, it works fine. Does anyone have the same error as me? Can i do indexing on the tables inside the hidden folder?
