WRITE-THROUGH CACHE
Menu location: GO > System > Write-through cache

The write-through cache allows Alan's Boot CD to act as a hard drive. Add, delete, and edit files directly on the CD. Add programs such as Adobe Reader, anti-spyware, utilities, etc.  Of course when you reboot your computer, everything is lost since what appeared to be written to the CD was actually written to cache memory, but that is the beauty of it. Unlike an actual hard drive, nothing will ever contaminate the CD.  Experiment with installing any program you want without fear of permanent damage. The cache size will automatically adjust itself depending upon the amount of total system memory:

What is unique about Alan's Ultimate Boot CD is the ability to run on systems with only 64MB of total memory, maintain a 4MB cache, run the Opera web browser, and allow remote access all simultaneously! If the cache fills up with unwanted files, you can always delete them with a single click.
