Low Disk Space

I have a windows 2008 SBS server it is showing a low disk space message.
It has a 59.9GB partition with 2.34GB free.
Yet if I select all the files on c it only comes to 31.1 GB this is with hidden files showing also pagefile moved to D: drive.
What is taking up all the space?

use treesizefree and run in admin mode to check it out
Please use treesize to see which folder is taking space

TreeSize is a good tool (I use it myself). The likely candidate is Shadow Storage.  

Open an admin command prompt, and type vssadmin list shadowstorage and see (1) how much you are using and (2) how much is allocated.

CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

Hi, you could use WinDirStat to get the disk space amount in the folders.  Here is the link- http://technet.microsoft.com/en-us/sysinternals

Check for Volume Shadow copies (Volsnap) are enabled or not. Volume Shadow copies might be consuming the Disk space.
I would say the space is all your exchange logs, if you run backups it should flush those out depending on what your using.  Run a windows backup if logs are taking up too much space or enable circular logging (although its not best practice)

Concur with Subhashishlaha, except be aware that some backup systems will also use Volume Shadow copy.  In my environment, it isn't unusual for the Backup client (IBM TSM (Tivoli Storage Manager)) to consume huge amounts of space in Volume Shadow copy.  For us, stopping/restarting the backup client is sufficient to free up that drive space.

Are you using ActiveSync or Black berryserver, they tend to eat space up QUICKLY.

also here is a freeeeee program that will show ANY and ALL files on a partition.

This will allow you to activley drill thru ctree and find what is hoggin the space.

also look under Program Files>Small Business> (something like that there may see a folder with a bunch of TEMP files for SBS management files that can be delete if you are not using the reports feature)
Ibet most of your space is within the c:\winsxs.  This is where w2k8 stores a LOT of stuff!

Winxsx does use a lot of space, but (a) it levels out and (b) Showing hidden files (first post by sykotex) would have shown this. .... Thinkpads_User

The question is about space that doesn't appear when the files in the file system are enumerated.  

The command "vssadmin list shadows" should show what's being consumed by volume shadow copy.
The other possibility would be space to which you don't have sufficient permissions to display.  (But I'd still put $0.25 on volume shadow copy having consumed the space.)

thinking back in the day, there was a case i was on, were client did show hidden files BUT was not showing system files,

Try SpaceMonger or one of many that can MAP out the drive, see what cha see.

post a screenshot or 2, let us see what you see.
