NTFS in general has a bunch of ridiculous, archaic restrictions that a more modern-ish one like ext4 doesn't. Does NTFS still not allow you to use a question mark in your filename?
the question mark is a wildcard, so is asterisk. slashes are used in paths. characters you can't use usually have implications for the OS. otherwise you can name your file pretty much anything.
Yeah, I think it's just funny comparing it with the usual situation on Linux, where there's even less restrictions. I believe you can actually put a newline in a file name, for example, though I'll need to check and come back later.
I'd need to rename a massive amount of files if I ever wanted to go back to Windows.
P.S. yup. Generally, just avoid /, null, and you're good to go.
In Windows certain words are reserved for system use. When naming files and directories, you are unable to use these words. Con, being short for "console", is one of these words. Con is also the Spanish word for "with", so a Spanish speaking user could not, for example, have a directory called "Fotos con Jim".
