Useful information to include:

When you drag and drop a file the spaces would be replaced with dashes or some other character to allow for easier management of the file inside of the CraftOS shell. Right now you need to use "" around the file name to make programs like edit and rename manage it properly. I should be able to make a PR for this as its in CraftOS

I don't think it makes sense to change the filename of uploaded files, that sounds counter-intuitive.

There's an open issue for improving how we handle files with spaces (#1256), which is probably worth fixing instead.
