Winrar says the disk is probably full whenever i try to extract/move a file, help?
First check how much discspace you have left on the disc you are trying to extract it to.
You can easily see it at My Computer
That's not much o.o, I think you should empty your disk a little a computer needs a certain amount of free space to operate properly after all. If you don't want to lose any files though you should put them on a external (did I spell that right?) hard disk.
I have one of 1 TB and I am pumping files to it every day and I still have plenty of space left on it. And my internal drives remain pretty much empty. Also when my computer crashes my files remain safe.
Ok that's enough pointless of topic ranting from me, hope it helped you a little though.
Which is too little, Windows needs a certain amount of space free when it runs.
Most likely the extraction is bigger than that, I would clean up whatever junk I have or move things to an external disc. 74.2 mb is very little
