What free online data storage service do you use ?

I'm interested in using an online storage for personal pdf's, spreadsheets, Flexwallet file, Word documents, etc. First question is how safe are they ? Second question is can you upload a file like Flexwallet, PhatNotes or other non-Windows type files to a data storage site (I just tried one free location and it took a Word document but didn't know what to do with Flexwallet). Basically, if a file can be stored on a USB drive can they be stored at any online site or do only special one's work with everything ? Last question, is free as good as one that costs money ?

I'm not sure if this will help you, but when I upload things like that I just use my hotmail account. Just email yourself the document, and whenever you need to get to it just download it.
