I have single folder of random images I've found online where I want to view the newest file first
I then I have another folder with various sub folders in which the files are numbered so I want to view those by file name so file_1, then file_2....etc

Yes you can alter the sorting via the thumbnails window but I believe this just applies to everything so I'm looking for a way to have different sorting depending on the folder.
One folder sorted by date and every other folder sorted by name.
