We know that the usual long path tool is a dead end so for this we use the usual exits.
1. Just format the drive and try again.
2. Use a Linux since it's more adept at such folders. No learning required. Read:
Apologies if this is redundant. I really tried to see if something like this was posted elsewhere.
With Win 10 File Explorer, I copy-pasted a folder that had only an *.mp4 from a laptop to an external hard drive, a WD My Passport. When I did, the original folder name was the same on the external hard drive, but the contents contained four folders and four files. The original *.mp4 was gone, and the folders and file names were variations of ]àα▀eå½╔.─£ and things like that.
When I try to delete a file, it tells me the name is too long or invalid, and to either Try Again, Skip, or Cancel. When I try to delete a folder, it tells me the folder is not accessible, and that either the file name, directory name, or volume label are incorrect.
If I try to rename either a folder or a file, it asks Are You Sure then tells me the name is too long or invalid.
Does anyone know a way I can delete the files and folders? I'm worried that what looks like some flavor of corruption could be a virus. I know it's not perfect but... c'mon Norton, do your thing!
