The easiest way to do this is get a copy of Tree Size (Jam Software) and run it. It will give you a sorted list. Very nice. It is a good explorer to as well, so it is well worth having.

Agreed... I've made loads of scripts over the years to do specific checks of such things but why re-invent the wheel, Tree size free - it's what I use, just drill down through big folders to see where the culprit is.  If you do want to script then you have to consider, do you mean a dir with files in totalling that size, or do you also count a dir with a hundred subdirs, all with a few hundred Kb in etc.

Try tree size anyway!
I've often used a tool called "windirstat". It gives a great visual representation of the file sizes and containing folders and of course is free.

We agree that Treesize Free is one of the tools to find your large folders easily. I'm using the portable version of Treesize, no installation needed and runs from a thumb drive:
you can type in search > 500000 if you want those bigger than 500kb

Hi Experts,

First thanks to all for those useful links,

After downloading & testing them, I was able to get an idea of whats going on in my pc..
However I am still missing one important feature, to select only folders (not files) that are bigger then XMB..
Maybe there is a way to get this from those utilities, can you please post a screenshot of it?

If you open a folder in Tree Size, the files list in size order as well. I use that feature frequently.  Just open the folder on the left and look on the right.

Hi John,

My problem is that I don't know in which folder to start looking at..
I have a Hard drive of 250 GB and there is only 20% free space,
I know some folders contains large backup files, but besides those there must be some large folders that I can definitely get rid off..

If I can only get a list of all folders on the C drive exceeding half of a GB, that would be a great accomplishment.
so i will then take a look at each of them and see which are necessary to keep..

Tree Size is easy.

Look in the Top Level on the left. The biggest files are likely in the biggest folder and/or listed separately at the bottom.  

Open the largest folders. There aren't likely a lot. A little exploring will tell you where the space is used up.

Also, in Tree Size, click on the top 100 files tab. That lists the biggest files wherever they are.
