Win 7 Temp Folder Size

[fetster]

I've ran out of space on my 1Tb HDD. Having looked at Foldersizes application, my Windows Temp folder is 862Gb. The culprit files are .tmp files and each of them are upto 50Gb in size.

Can i simply delete them?

I think it may be from cctv software that I run because everytime I use the software the disk fills up.

Thanks for the advice guys
