I bought a Sony VAIO in 2002 (yeah, I know - it's OLD), with Windows XP Home Edition (256RAM/Pentium 4CPU/1.50Ghz). It has a partitioned hard drive - with my primary (C) drive being 16GB, but only just under 4GB still free. The D drive has 40GB, with 32GB still free. Performance on my PC is SLOW and I have tried numerous PC clean up products (all free) with nearly no results.
Primarily, only system and program files are retained on the C drive; all of my personal files are stored on D drive, but are backed up on an external drive.
I also use AVG2012 antivirus (free), MalwareBytes Anti-Malware (also free), and Glary Utilities (also free - OK, so I am cheap) for protection/performance assistance. A couple of years ago, I also installed ZoneAlarm (yeah, free) to help stop processing interuptions with software checking for updates, with the hopes of helping performance. And, lastly, I defrag at least twice a month.
I plan to get a new computer eventually (or sooner, if absolutely necessary), but I really only use this one for internet access, email, MS Office products, Adobe Photoshop, as well as some really simple, old games. So, I thought if I could move some of my extra space from D to C - or if I have to remove the partition altogether, I might get another year or two out of this one.
I am no computer 'guru', so I am looking for very user friendly software to adjust the size of my partitioned hard drive without a lot of complication, and of course, for free if possible (maybe, I will have to pay for this one - OK). I also don't want to have to re-install all of the program software if at all possible.
Can anyone help advise me!!!!
