I want to know if there's a service that could do the trick for me. I want a client for a cloud service like dropbox, Drive, OneDrive etc, which would only download the file and all the child files needed to the computer when I open it, and offload those to the server when I'm done, just for the purpose of freeing space in the local drive.

More or less like a NAS would do, where you can see all the items, but they're stored somewhere else unless you open them and the download/stream begins.

I would prefer freeware, but if a paid one is the optimal option, I'd go with that.

Must have:

  1. Ability to download files requested by other software (Like an .exe which needs config files or additional data).

  2. Selective sync (In case I want some files pre-downloaded).

  3. GUI and some type of listing or file explorer to see all your downloadable content.

  4. Offload temporary files to the cloud service to free storage when not used.

Would be nice to have:

  1. Portable version.

  2. Recent and/or frequent updates.

    Are you OK with mounting a WebDAV remote folder as a drive on your computer?

  • The downside is that my main will have to stay on 24/7... But it's better than nothing. Can you tell me more about WebDAV? I researched for a bit and don't really understand how it would work. If the files would keep stored, if there's some type of GUI. I think it's somewhat similar to a NAS, but for external connections?

  • With WebDAV, everything is stored on the remote server. Nothing is stored locally (or only temporary caches). Only when you read or write a file, or browse the file system, network transfers occur.

I found a piece of software called Expandrive http://www.expandrive.com/

It is NOT portable, but what it does is map the cloud service you selected onto a network drive in your computer, like a WebDAV or NAS would do. The sync occurs in the background and the files are not downloaded until they are requested by any software.

It is a PAID software and it's not cheap.

Does anyone has any new software to show me?
