Found the Frozen Bubble High Scores:

Inside the /home folder for the user, locate the file: .fbhighscores

thats [dot]FBHighScores - but in lower case.

Each user account that has played Frozen Bubble will have this file to retain the "user" accounts high scores. You want to look in your wife's /home directory for this file, and copy it off, unless you want to have it evaporate, if you decide to go with the ext3 file system.

I agree with Dave on using the ext3 file system, it is set up to keep track of file information, in the case of failure, it has a better chance of avoiding the corruption. I use the ext3 format, and have not had any problems, but then again, I used to live in Tucson, AZ - and lightning hits were common, so I have a UPS on any computer system that I run - its cheap security. IMHO
