This evening I have been going through my computer, looking for duplicate files and reviewing the software I have installed. It was time to tidy up.
I moved some files around, deleted some duplicates.
I went through my applications, updated some to newer versions, tried to work out what some applications do that I have never used before, and deleted things I did not need.
It was a good exercise to do actually. I spent a couple of hours but learned some things as well as freeing up a few GB on my laptop. I would recommend you do this too.
