Unsanitized filenames about gdown

[OmarAHex]

Another note, google drive allows slashes in file names, meaning by the time the download function receives the output path it is impossible to tell whether that slash is part of a file name or represents a folder, so atleast some part of the sanitization would need to happen in the download_folder file. (The error raised here is related to trying to write to a nonexistant folder)

Also, line 185 in download_folder.py does "file.name.replace(osp.sep, '_')"
but this is not sufficient for windows
on windows, osp.sep is "\", but "/" is also a valid separator, which gdown ignores, I think this entire issue could be resolved by replacing that line of code with a proper sanitization function

@OmarAHex Can you give me an example so that I can reproduce?
