BMdoobieW,
You will note that SetiDriver creates numbered directories which hold each of the cached WUs. You need only copy those numbered directories to SetiDriver on another machine. You will want to check the destination machine and see what the highest numbered directory is, then renumber the source directories to numbers above that. Stop SetiDriver on the destination drive and copy the re-numbered directories. Restart SetiDriver and you will note that the cache size has increased to include the number WUs. Once you have confirmed that things are working properly on the destination system you can then delete the SetiDriver directory on the source system.
If you want to put them on a system that isn't running SETI, then copy the entire SetiDriver directory with all subdirectories. There is no need to install anything; just copy it.
Good uck and let us know how it goes!
