Hi Manos,
The structure is simple: mediafile directory contains subdirectory for
each weblog (named with weblog handle) and each subdirectory contains
files (named with a GUID value).
If you define both an old updates directory (i.e. uploads.dir) and a
new mediafiles directory (i.e. mediafiles.storage.dir), then Roller
will attempt to migrate your data from old to new. When Roller is done
it will place a migration-status.properties file in the old uploads
directory to indicate that it has been successfully migrated.

PS. see JPAMediaFileManagerImpl.java for the code described above.
