In the Mac System 7-ish days, people used to earnestly warn each other not to name a file '.Sony' (a special name reserved for the floppy driver) as it supposedly trashed your HD. Although I've never heard of anyone reproducing it.

Trying to name a folder "trash" led to the error message "The name 'trash' is reserved for the operating system."

I'd try it myself, but I've only got my phone with me.

7.0.1 might be a little late, at least, for the supposed catastrophic results. It doesn't like the file at all but nothing dreadful seems to happen.

I tried it in that and System 6 (https://archive.org/details/mac_MacOS_6.0.8); System 6 actually didn't care at all. An interesting bug.

I haven't actually done so, but earlier versions are available if you know where to look (https://archive.org/details/mac_Paint_2).
