It also shows you file size distributions, so you know for which file sizes you can optimize your hardware settings (cluster size, stripe size, ...) for.


Free apps to show the foldersize of NETWORK drives

Comment by em4020
about JDiskReport Jun 2011

Free applications to examine the foldersize of NETWORK drives:

FreeCommander (portable) , JDiskReport (portable usage with the executable Java-File jdiskreport-1.4.0.jar) ,

WinDirStat (portable):

With TreeSize Free (portable) you can only examine LOCAL drives.

The free TreeSize Mobile for "Windows Mobile" is able to Manage the disk space on your smartphone:


FreeCommander can show foldersize and sort by foldersize

Comment by em4020
about JDiskReport Jun 2011

Beside many other useful functions FreeCommander shows (also sorted) how much space the files and directories consume on your disk drives, similar to JDiskReport or TreeSizeFree, but as opposed to "Treesize Free" also on network disk drives.

To sort the folders using the size of folders you must select "Size of folders" in the menu "Folder":


JDiskReport shows also the size of network directories

Positive Comment by em4020

In difference to TreeSize Free shows also the size of network directories.
