In addition to the Windows command described in last night's tip, you can also find the size of a master file table with an appelet available on the Microsoft site, called NTFS Info.

NTFS info was designed by Mark Russinovich. After installing it on your PC, it allows you to run a new command (in admin mode). Use the cd command to change to the directory with the ntfsinfo.exe file that you downloaded. Then enter the command:

ntfsinfo.exe c:

. . . in order to get information about your C drive. As you can see in the screen grab below the size of the master file table is given in MB.
