A file system on a server shows that it is dangerously close to running out of free space. It contains many directories, which in turn contain many more sub-directories. How to find what files(s) are taking up the most space?

du -h FOLDERNAME
works in a linux command line.  But there's no such answer for DOS.

There really isn't any good or efficient way to do this from a DOS command or BAT script. There is no single command that will report the size of a folder, including all files and subfolders under it. And DOS only has 32 bit precision in it's math functions, so you can't do a lot of calculating yourself with numbers that are as large as file systems, etc.

Powershell (and even VBS scripts) has a lot more power here, but that would be a different set of skills you'd have to acquire it sounds like.

In the DOS world, leveraging an existing utility is about the best way, otherwise you'd be writing some very large and tricky BAT scripts that wouldn't really be that useful anyway.

The only other way to approach this would be to leverage Windows WMIC command line utility to search the entire filesystem for files larger than some size, like larger than 1GB or something.  And then work from the result list.

A trial of TreeSizePro is the best at this sort of thing.

However, if you are really low on space a small self contained executable such as SpaceMonger.exe will also do the trick.

it might be you need this that you can download disksum utility execute code and copy it  into your system32 directory and please make sure it can be used globally in any path in
order to find the largest file size

Hope I understand your question completely, if not please point it out

Hi,

There are a lot of programs out there to run a report on where your disk space is used - one that I use often is TreeSize (http://www.jam-software.com/treesize_free/.  It doesn't run continuously in the background to monitor space, but runs as-needed and gives good reports.

Hope it helps,

To quote an advertisement, there's an app for that.

The best ones I would recommend are:
WinDirStat:  http://windirstat.info/

SpaceMonger:  (I prefer the free old one) http://www.sixty-five.cc/download/  
Tap the "Free Software" and scroll down to 1.4

These will show you graphically where your space on your drives is going.

Good Luck.
