Aah, it does include "PNG". So the filter on the path not only the name of the file...   

Agreed. I actually thought it would display all the (filtered) files under subfolders. In other words, in this case, all the PNG files in the folder and subfolders.

I Like the idea of being able to use subfolder filters. 

I just tried to setup a filter for some videos in "Videos" folder and was trying, .*\(m4a|mp4)

The results were kind of surprising. A max depth would probably be useful and since you already pick the base folder for the pin, a full path would probably not be necessary.

thanks

Regex (Regular Expression) has a fairly complex syntax and not easily understandable by the average user. Try searching on the internet for Regex and you will find a wealth of articles and How-to tutorials on the subject.
