Re: Help please!
You can use the other volume (1TB) like it's a memory stick (albeit a permanent one...)
Just go into your documents, downloads etc and copy the files over to the 1TB drive (you can create folders in it with names if you want).
Also, as crazyman helpfully suggested, you can download the program called TreeSizeFree which will tell you where the space is all being taken up (if you don't know where the files are kept).
It sounds like your main hard drive is an SSD (Solid State Drive) and possibly between 30GB and 60GB in size? The idea is that you have the operating system installed on there, and any programs/files you want to open quickly and take advantage of the SSD. Then any pictures, videos etc you have stored on your PC you can move to the 1TB hard drive for more storage space.
