auf? - no idea. I just have .aup files, and then in the data folder .au 
files.

Ok, found something here: viewtopic.php?f=13&t=6171&p=24804#p24636

     The reason Findelsplurb may have problems is that he has .auf 
summary files, which are not complete audio data. These probably 
indicate that the projects depended on audio files imported into the 
project, which will be on the other computer. These audio files are 
required to open the project even if you have the .aup file

=======

Note that Audacity saves a project, but not a WAV file. To do this you 
must export as a WAV file.

We recently noticed that there are a bunch of extra files that end in .auf They are all about 1000 KB and have a name along the lines of b02720.  There are TONS of these files. We are wondering what they are and if it is safe to delete them or not?
