Help please, no disk space!

[TimTom]

Really sorry if this is the wrong place to post such a basic question but I need some help, please.

My laptop is telling me that the C drive has run out of space (0 bytes available of 22.9GB). But when I look at storage space, it shows the following.

Apps 35.9 mb
Pictures 108 mb
Videos 8.00 kb
Music 0
Documents 236 mb
Downloads 13.7 mb

Where am I going wrong???

Thanks

Thanks for the helpful replies.

Apologies for my ignorance but if I use a storage cloud am I right in thinking that wouldn't help much as the documents will still need to sit on the C drive?
