The short answer is yes.
Select the Advanced > Document Processing > Batch Processing menu item
Click the New Sequence button on the Batch Sequences dialog
Add a name (e.g. Password Sec) and then click the OK button on the New Sequence dialog
Click the Select Command button on the Edit Batch Sequence dialog
Scroll the listbox on the left until you find Security
Highlight Security and then click the Add button
Highlight Security in the right listbox and then click the Edit button
Select Password Security from the Security Method drop-down list
Assign the security settings you want to use and then click the OK button on the Password Security Settings dialog
You will be asked to confirm the passwords that you've assigned
Click the Close button on the Document Security dialog
Click the OK button on the Edit Sequence dialog
You are back to the Edit Batch Sequence dialog at this point and you've completed one of the three items. Here is where Batch is powerful. If you decided to run the command on a Selected Folder all you need to do is drop all of the unencrypted files into the folder you have selected and run the Batch Sequence. If you click the Output Options button you can assign new names to the files so you can keep the unencrypted original separate from the newly encrypted copy.
I hope this helps,
This is great news!!!
I will be rounding up my customers files to get this done tomorrow. I'll post my results.
Thank you, thank you!
