Thanks to teenage children, I’ve had cause to try to clean up my hard disk thanks to extensive music and film downloads.
I had tried to find the files manually, but had a lot of trouble locating the offenders.
I searched and found Disk Recon.
I was able to find all the big files easily, and to clean up.
It’s an older computer, with “limited” space (5yo, it seemed like unlimited at the time).
And it’s got some nice features- like finding “duplicate” files- those with the same size and extension, with different save dates.
It has a 30 day trial period. That was all I needed to clean up my hard drive after two teenage daughters having left home recently.
