Thanks for the feedback folks.

I've been looking into a paid service. The free ones freak me out too much. And if they don't allow anything adult then I'm screwed with them anyway.

Basically, my external drives are full, so they're out of the question. I installed Ubuntu alongside Windows and half my HDD went with it. Ubuntu isn't working properly, after much troubleshooting and command prompting, so I want to uninstall it and/or reformat Windows. But I have to back up all my files first of course. This is why I need some place to back up my extra stuff. My current HDD is getting quite full.

I'll go with a paid service and let you know how it goes.

Thanks again
