I have a large collection of files to share for everyone, and I'm looking for a cloud service that matches all or some of these needs (sorted by importance):
- Allow others to upload, download files, create folders and move files between folders, but restrict them from delete files
- Be recoverable if something goes wrong (revert deletions)
- Visitors can view without downloading (mostly PDF)
- Have stat, or can integrate with Google Analytics
- Free for a couple GB (at least 3 GB)
- Visitors can have a synced copy in their hard drive
So far I'm using Google Drive, but the edit mode allow others to delete the files as well.
