Just add the extension back and the files will work again.

You would be better off using auto organise files (CTRL+R) to change your filenames, that will stop that mistake happening again.

I didn't realize it last time but I was finally able to replicate the error and, in this instance I was editing the filename, but forgot to include an extension before confirming the change. How I could have done that to multiple files at once I'm not sure, but I'd wager it's related to that. What an odd thing to happen, becoming a blank, faceless file with no identity whatsoever.

I couldn't find another topic about this, but admittedly it's hard to search for. I don't know how much more I can describe it, either. Their icons are now just a blank piece of paper instead of the music icon, and they won't open in any program. In their properties, the filetype is simple 'File'.

4 0 1 1461 is the version I'm on.
