Hey pling, I work on the OneDrive team. We definitely don't do the type of content scanning that you're describing. I wouldn't be comfortable with that. The only time we currently use file hashes for automated takedown is when known child pornography is re-uploaded to the service after being reported. For copyrighted content, we have to respond to DMCA notices like other services. Sharing content to the public and getting reported by a third party is the only path for that. And in those cases, you definitely get a specific notice about the takedown. The web UI would also show you exactly which file was affected, and prevent you from sharing it again. It doesn't just delete files. (That would be unacceptable.) Note that there's currently a 2 GB file size limit. It seems like the most likely explanation is that you put a large ISO in your SkyDrive folder, and it never succeeded in uploading because it exceeded the limit.

Will the file size limit ever be upped? I got dozens of movies, ISOs, and database backups that OneDrive can't sync.

  They really need to increase the maximum file size to be competitive. As a comparison, Dropbox files can be up to 10 GB each[0], and Google Drive files can be up to 1 TB each[1].

    Its disingenuous to say that Dropbox has a file size limit of 10GB, when the first thing written on that page you cited says otherwise... The 10GB limit only applies to files uploaded through the web interface. Files uploaded through the OS/mobile client have no file size restriction.

      Good catch. I skimmed that page quickly and saw 10 GB and didn't look closer. Sorry for the confusion.

I'm not sure how you can explain it then. The file was 600Mbish. It successfully uploaded via the desktop client then was later downloaded on another machine via the desktop sync thing. Later that evening it was gone. I didn't delete it (it wasn't in the recycle bin) and I confirmed it was the correct live account I was signed in as. To be clear it was still on the source machine but not the destination. No antivirus had quarantined at either end. That by elimination would suggest that either: 1. There is a reliability limit somewhere which is unknown and unpublished or a synchronisation bug. 2. You're unaware of a process or a false positive. I should have opened another account to test this against with the same file but to be honest if I found a bug, windows live support has been abysmal. Hell they couldn't even work out how to close my account when the close account page refused to work...

  Yuck. Sorry that you had a bad experience. It sounds like you hit a nasty sync bug on the destination machine. We've been patching a bunch of issues with client sync reliability over the last year. It's hard to diagnose at this point, but please reach out if you can reproduce it on the current version. FWIW, I can say with confidence that your issue had nothing to do with the fact that the file was an Office ISO.

    Thanks for your reply. That fills me with a little more confidence. However, elsewhere in this thread someone else raised a valid question: How do you handle child porn filtering? I have three children and take photos of them. I am worried about false positivies.

      Why don't you encrypt those pictures before getting them out of your control on the "cloud"? I would extend this suggestion to every other file but those in particular kind of scary me to be available somewhere else without encryption.

Do you ever close an MSA after X amount of takedowns? Whether it be for DMCA notices or otherwise?
