Yes, you done it successfully to check the disk space.
I wish the font size used at "Missing 6.5 MB to save home" may be bigger is better.
For me it is too small to read in 1280x960 resolution monitor [:-B] [8-}] [B-)]. Also change the window title to 'Not enough Disk Space'( [:-?] Its not a 'Error', Its a warning, I think).
