How to load filenames with specific format?

I'm in the process of working with a massive archive of images (over 120,000 in this subset alone) and trying to add only files that have a filename with the following format: 1234-5678.jpg. The files have several different image format extensions, not just .jpg. There are some .webp and .tiff files in there, so I can't assume the extension is only 3 characters.

I've tried several different PCRE expressions in the regular expression match box and can't get any to work. Does anyone have any suggestions?

Add Directories...

Select a folder from the list

"Include subfolders", if necessary.

"Regular expression match": ^\d{4}-\d{4}\.

That will match a string of 4 digits + a hyphen + 4 digits, starting at the beginning of the filename and ending with "."


Alternatively you can drag a root folder containing all your desired files into the list.

Select "Add the files in the folders" and "Include subfolders" (if necessary).

Then use the same regex.
