In Windows , we can find free space of a disk drive using fsutil command. This command’s syntax is shown below.
fsutil volume diskfree driveletter
drive letter can be any local drive.
Ex:
C:\>fsutil volume diskfree e: Total # of free bytes : 45569585152 Total # of bytes : 52427898880 Total # of avail free bytes : 45569585152
Note that this command should be run from elevated command prompt. See How to open elevated command prompt
The above fsutil command works on XP, Vista, Windows 7, Server 2003 and Server 2008.
Can someone tell me the difference between free bytes and avail free bytes? Every time I check the free space with this command, the two values have always been the same.
I guess there can be a difference when the administrator has set up quotas : although there are 10Gb free, only is available to your user.
