Someone I collab with uses OneDrive. I retrieve MANY large files from them and I've had tons of problems downloading from OD. I can pretty much count on multiple download failures for every batch of files they send. I have to make a list of/keep track of/babysit all the individual files before, during and after the downloads to make sure I've gotten everything instead of just starting the downloads and walking away like I can with Dropbox.
Eventually I get them all but sometimes I have to restart individual downloads half a dozen times or more. Like widdling away at them until I finally get everything. Real PITA time waster.
Of course Microsoft would affiliate themselves with something so annoying.
Dropbox has been rock solid for me and I use the free version. The only weird thing that happens is sometimes the file links I receive try to open in their "Preview/Player" thingie but I think that's more about how they are uploaded than anything else.
Anyway... I should probably let some people know about this so they don't lose files. This is reminiscent of the Gobbler fiasco (which thankfully I didn't bite on).
