Uncompressed .hmxp and stored locally.
It definitely shouldn't be anything to do with your project directly. It all sounds much more like some external problem in the Windows file system.
Actually, while I thought it was unrelated, earlier in the day, Explorer froze and I had to kill and restart it... apparently, not unrelated at all.
Generally, you should always be able to access the previous versions directly from within the project with the history function. Just click on the gear icon in the top left corner of the editor window and select Show History.
I don't have a gear icon in top left, but now, I sure would like something that gets me directly to the history. There's a gear icon in the Project tab, but that's for properties, templates and options. (I have checked all the Configuration > Miscellaneous > XML Topic FIles boxes that have to do with history. )
Is there perhaps an updated method to obtain that icon, one that's not yet in the help file?
