Has old wallpapers in it. they're jpg files with the extension of png.
I assume this is where you store the temp file before displaying it as wallpaper?
How long should it be keeping them there?
I have 5,566 of them in that folder going back to Feb 1 2016.
That's 4.8 gigs of images.
I'm going to delete them, but can you please keep maybe only a day's worth. That's a lot of temp files.
