Working on the ethos that "digital data doesnt exist unless it exists twice" I copy all zips and exes as they are downloaded into one blank "DATA" directory and copy the extracted data into a blank "Runtime" directory, I sort this as I go for better file management. These are copied via a data card to a seperate computer (at work) as and when convenient, then burned to CD when it reaches 600Mb. No need to burn Multi-Gigabyte back ups, and re-installing is a doddle, just copy each Runtime CD sequentially. Only use the Zipped data to re-install items deleted in any clear-ups. Anything for an easy life B)
