If you wanted to select all files under the “images” folder, you would enter: images/**
To select all files under the “june” folder, you would enter: **/june/** or images/**/june/**
And lastly, to select all files with the name “car” in them, you would enter: **/car* or **/*car*
A few caveats:
1. This field is case-sensitive.
2. If you do not include the * character, the field will strictly match file names, that is, neither june nor images/ would match any of the above files.
3. The forward slash "/" file path character must be included with ** if your files are in sub-directories. *car* will not match any of the above files, and neither will */car. Only **/car will return images in this case.
