Where can I store various files (documents, pics, sounds and videos) up to 2 GB online for free? If this means that I will have to store them on various sites and servers, it's ok.

I don't know anything about this place, but I came across it doing a search. Streamload 10GB free

You could also try getting a bunch of yahoo id's, each one you have comes with I think 30mb of free briefcase storage.

Also if you have a gmail account, there is a gmail shell which allows you to use your infinite gmail space for storage of normal files, which is pretty cool.

You can find the Gmail Drive extension Here

Now that Gmail offers inifinte space you could store all of your stuff there.

I have tried the shell extension for gmail and it worked fine.

Thanks a lot, I'll try that!
