I have a folder with 85,893 files, according to the folder Properties tab and my memory of its contents. However, Windows Explorer is currently showing just 1490 files, which appear to be the first 1490 alphabetically. AC Browser Plus finds 1811 files at the beginning of the alphabet, Bulk Rename Utility matches Windows Explorer. An image viewing program (ThumbsPlus) is finding 8041 or so files, which appear to be the first 1800 or so alphabetical plus newer ones that it has thumbnailed with its own directory information. Obviously the files are still on the hard drive (for one thing, ThumbsPlus can access the files that it has thumbnailed but aren't appearing elsewhere) and the file directory has been damaged somehow. There must be a way to fix this, eh?
