I do not remember the exact steps.
But I did use the Palm Desktop and after I synced both units being careful to name them accordingly and NEVER the same name I went to the Palm Desktop software to copy and paste content from one device to the next.
Again, I do not have a step by step for you.
I have a Z22 which is failing. I also own an unused Tungsten E. Can someone give me a method to transfer the backed up Z22 data on my computer to the Tungsten E?
