Being mired in hard disk space poverty sucks. Having your operating system keep reminding you of that every minute or so sucks even more. And to add to your woes, it's promise of helping you cleanup your hard disk to make more space falls apart when there really isn't anything it can suggest you remove.

So that's how it is recently. Look at what's in my "anime" partition: episodes of Naruto, Chrno Crusade, Full Metal Alchemist, PLANETES, Shingetsutan Tsukihime, Gunslinger Girl and newly-found Mezzo TV. And 3.33 GB invested in Neverwinter Nights together with the Shadows of Undrentide and Hordes of the Underdark expansion packs. Those and more on a 20 GB hard disk in my laptop. I live day by day, deleting anime as they are downloaded and watched, or transferred over to my desktop (which, thank heavens, has 80 GB).

Anyway, all 3 of my partitions are often nearly full, and Windows XP keeps trying to be helpful. I don't like being "helped". So this is what I did:

  1. Opened my registry with regedit
  2. Found the HKEY_CURRENT_USER -> Software -> Microsoft -> Windows -> CurrentVersion -> Policies -> Explorer key.
  3. Created a new DWORD value named "NoLowDiskSpaceChecks"
  4. Set the value to "1" to disable the low disk space notifications

Meh!
