low disc space message. I was instructed to purchase and external hard drive by a computer salesperson. But, even after transfering files to an external hardrive, the memory did not improve. I am also unable to defragment b/c of low disc space. Attempted to compress files, but after the application runs, The files do not alter. I am also now getting various error messages such as 0xc00000135. I deleted my .net framework to re-download so that I could update microsoft, but I can't tell which ones I need to download. Plus, since I don't have any disc space, I can't download anything....is this a communication error in the system? HELP!1 person needs an answerI do too
