Sometimes when creating a new file, especially Proton Doc file, the file name actually conflicts with Windows but Proton Drive web app doesn't tell.

Only until I saw it in Proton Drive desktop, I knew about naming conflict.

For example, I made a file name similar to this with slashes on Proton Drive web app: CPU/GPU Costs

I know that clash only happens on Windows, not Linux (limits this slash only and not other chars), but maybe a small alert on web app should be nice.
