Putting a slash in folder name creates subfolder

[sweetpea22]

I think this was intentional, but creating a folder with name "Design/Illustration" creates a subfolder. Is there a way to escape this or make a different shortcut? Worried users would find this surprising. What do you think?

So from the filesystem perspective it's rather feature than a bug :)
Like if you upload several files with full names like:

/folder1/folder2/file.txt
/folder1/file.txt
/folder1/folder3/Very Important Papers.pdf

And you don't need to create all those folders there will be there for you automatically.
So I'd treat slashes in folder names as a way to create folder structure.

Okay, that makes a lot of sense. Think this is a good one to AB test with users, and see if it's acceptable to them when they're entering a name from text input

Prevent user's from inputting a / in the folder name, and check whether file name is validated as well
