We all need space….
Once upon a time I had a 250GB HDD, and it was back then large. Everything I needed was on that disk. But as the files grew, so did my hard got smaller. On that disk, I have lot of pictures and music, maybe some movie and bunch of documents. Suddenly I ran out of disk space…
Quest No.1 – Understand consumption
My first quest was, first to find what consumes so much space. For that I used a free disk analyzer software called Space Sniffer. It is a standalone exe file. 
You can choose a drive, or a path. works also with UNC paths. Then press Start.
Very intuitive and practical software. It graphically shows the size of every folder or file. This depends on scaling the details. You go a level deeper by clicking on a particular square. From this screen, you can also open, edit and delete files and folders. Best of all, this software is free, and at the end you can create a log file.
Quest No.2 – Duplicity
As the files grew in numbers, there has also been a problem of some laziness. Some files got duplicated. After googleing and trying couple of software, I found one, also free of charge. Fast Duplicate file Finder from MindGems. Easy to install and easy to work with. 
Works with data files, audio and picture files.
For test I have crated a three folders, and put various duplicate files in them. First add folder, and setup scan properties. If you think files are similar, then choose similar (but slower method) or find 100% identical. I will leave it at 100%. Press SCAN.
After it scanned you get report like this, sorted by duplicate groups.
Duplicates are automatically checked. So you can probably delete them and save some space.
So, that’s how I got several GB of space free.
Good luck
