I had a habit of copying everything when I backup my old computers in the past, system files and all. The whole volume.
I recently purchased a new hard drive (my 4th 500 GB drive). Now all 4 of them are full with about 250GB left on the newest one. Its crazy. Here is why.
On the other 3 drives are entire copies of old volumes from different computers I had. I would estimate that in most cases, the system (OS, various programs like Office, Visual Studio etc) are taking up huge amounts of space.
Is there a tool that can scan the drives, match the various files from above, and remove them for me, leaving me only with the files I need. I would not mind if it did not get everything. But even if it got 50% of the system junk it would be helpful.
Yes I learned the lesson of keeping my files in a single place now separate from my system and backing them up properly. But I cant afford to lose the old stuff as much of it is tax and business related.
