I think I have some good news for you. 

If the installer for PDF reDirect Pro finds the Batch settings files in the "right" location, and it will recreate them for you automatically. So, this is how I recommend that you proceed:

On your old computer

• Go to the following folder (assuming Windows 2000/XP):
• C:\Documents and Settings\USERNAME\Application Data\PDF reDirect
• Copy the following Folder to a USB Drive (or floppy, or whatever):
• Batch_Printers
• OPTIONAL (to what you are asking)
• Copy your settings file: Prefs_v2.ini
• Copy your "Stamps" folder too if you created custom stamps
• IGNORE the "Temp" and "Bug_Reports" folders
  

On your new computer

• Uninstall PDF reDirect (if installed)
  
• Navigate to:
• WinXP: C:\Documents and Settings\USERNAME\Application Data
• Vista or Win7: C:\Users\USERNAME\AppData\Roaming
• Create a new folder called "PDF reDirect"
• Copy all of the data from above in the new folder.
• Install PDF reDirect Pro
• you should see your batch printers get recreated automatically.

Note: your registration data is encrypted on the old computer and cannot be copied to the new computer, so you will need to re-enter your key via the "Register" button.

Cheers!

An additional note for the users of the Beta v2.2.9xx (in preparation for the upcoming v2.3.0). Please "unshare" all of your batch printers first before following the procedure above.

You are welcome!
