I've got a Mac, so it probably won't run on my computer. (Besides, she abandoned that app long ago and doesn't even read Kindle books anymore.) I rarely look at the file list of books, and when I do it is to find the one I want to add to calibre to free it from bondage. So Finder (the Mac equivalent of Windows File Explorer) is what I use and looking at all those ASIN file names is useless. If they had titles for file names you could quickly find your book and add it to caliber, but not so much with ASIN file names. At least the latest file date works, but it is clunky to do that.
