How to give all Files in a Folder a new Lens Serial Number?

[Gabi_S]

I try to change the Lens Serial Number of all Pictures in one folder.

I´m able to change it one by one. How can I change all pictures in one step?
I don´t want to change any other data.

Can anybody help me?
Thank you!

Can you select a directory in the GUI?  If so, this should work.  Otherwise you should be able to select multiple files I would think.
