I too am trying the same; backup my fav's 'cause I have too many to track down again among all my refills! I read the reply on backing up/copying the .prf file. I've looked in the recommended directory, but I dont have a "Reason Preferences.prf" file... I DO however have a "Reason Data.dat" file in the directory. (I'm running Vista). Can anyone confirm that these 2 files are one in the same? I have all hidden files visible, and searched my hard drive extensively and I just dont seem to find the *.prf file. Thanks in advance!
