Thumbs.db

Recently I had to move 200GB from one hard-drive to another.
It was imperative to make sure everything was copied successfully.

Using a binary comparison tool would take a really long time. So I only check the total file size of all files copied and the number of files.
I tried copying these 200GB files several times and never succeeded. I was too lazy or busy to investigate until today when I got really pissed off.

It comes out that the difference comes from thumbs.db files.

Thumbs.db is a thumbnail cache used by Windows XP and Windows 2k3 Server.

How to stop the creation of these files:

  1. Click Start
  2. Double-click Control Panel
  3. Double-click Folder Options
  4. Click on the View tab
  5. Check off the circle next to Do not cache thumbnails
  6. Click the Ok button
