I'm after a list of the largest files on a windows box, i.e. Not just in one folder, but anywhere on the disk. Is there any easy way of getting this?


Do a windows search on you windows drive with "*" joker that mean all file, and specify a minimum size let's say of 40mb, than you'll have every file on you system drive that are larger than 40mb.

Hope this help.


Check out this app: WinDirStat

This will show you graphically as well as a hierarchy/tree map. This software is free and open source (GPL) and works really well.

  • +10! windirstat is awesome – hasen May 13 '09 at 13:18
  • I have always used Sequoia View, but just installed WinDirStat to take a look at it. Very nice. I think Sequoia View lays out the Tree Map a little better and is more responsive. I do like WinDirStat's ability to select a file type and see it highlighted across the entire drive. – Keith Sirmons May 13 '09 at 14:50
  • @Keith Sirmons - Do you know if Sequoia is a branch of WinDirStat? They look very similar and since WinDirStat is open source this is very possible. – Andy May May 13 '09 at 15:21
  • Sequoia View's V1.1 original publish date is 11/9/2000. It was about 5 years ahead of WinDirStat's V1.1.2 release on 7/16/2005. – Keith Sirmons May 13 '09 at 15:40

Install PowerShell. Then run this:

dir c:\ -recurse -erroraction silentlycontinue | sort length -descending | select -first 20

That'll give you back the top 20 largest files on C:.

  • This eats up all the memory and throws an OutOfMemoryException. – pkr Sep 10 '18 at 14:40
  • Great out-of-the-box solution, thanks for posting. – fusion27 Jul 11 '19 at 14:03

If you are doing this regularly, you might look at tools like TreeSize Pro or SizeExplorer (although the latter seems to nob be as recent).

  • @Marc-AndreR., Do you mean TreeSize or do you mean SizeExplorer? – Pacerier Mar 17 '15 at 19:59
  • @Pacerier : TreeSize is definitely more recent and maintain than SizeExplorer or WinDirStat. That said, both does the job but I do have a preference for TreeSize. Hope this help. – Marc-Andre R. Mar 18 '15 at 10:52

Install Sequoia View

It will visually show you your large files and large directories. It makes finding where all your space disappeared very easy.

Free and < 1 Mb in size.

enter image description here


PowerShell (extending answer 7768) across multiple drives:

 "c","e","f" | dir -path {"$($_):\"} -rec -ErrorAction SilentlyContinue | sort -desc Length | select -first 20 | ft FullName
  • Are you certain that this currently works? – Nae Sep 17 '18 at 7:29

    @Nae Over nine years ago: I can't recall. But the new version definitely does – Richard Sep 17 '18 at 9:15
  • Yes it does seem to be working now. Thanks for the update! – Nae Sep 17 '18 at 9:29

A very simple way to do this is to type the following into the search box in Windows Explorer:

* size:gigantic or if you are after slightly smaller files go for * size:huge.


My favorite is Disk Scanner by Steffen Gerlach:


Standalone freeware, 157K. Takes a little time to build the report, but the circular graphic is very intuitive and informative.


Yes and it is free: Folder Size
