Hi Tony
Depends what the 'stuff' actually is.
If you want the OS (being win98) or some of the apps, you may well have problems. If it is just a data file, you will be ok.
The distinction will be if registry entries are required, and if the ones you have in the active partition are suitable for the app from the other partition. If you really want these, it is possible to export and import them, but be prepared to do some research!
Have fun!
