Hello! Using this Google App Script code makes it possible to do file requests (even anonymous ones) using Google Drive. The implementation provided uses user input to create folders within a specified folder but you can remove that feature pretty easily for anonymous uploads.

I've limited it to 100MB transfers but you can also remove that and test the limits for yourself. I've successfully done up to 200MB at one time which is pretty huge for being absolutely free and customizable.

Thanks!
