You know that folder option to half the text name for files that are compressed to be colored blue? Well a lot of my files were like that, and when I checked their advanced options, the compression option was checked.
I uncompressed them all by goin to Run..., then running "cmd.exe" and then typing the following commands:
COMPACT /u /a /s /i
But I still dunno why it did it in the first place, I mean I still have tons of HD space left on the drive, unless windows automatically compress files that are rarely used. But it even compressed a lot of files in the Windows directory.
