Need undelete Blackberry phone SD card data?

Hello, do you know how to undelete pictures from SD card from a Blackberry phone? While using my Blackberry cell phone 64GB SD card on my PC, one of the picture folder was deleted with shift delete and found nothing back from Recycle Bin. And, after reading related articles, I knew there were many data recovery tools, like some free Recuva, Undelete Software and iCare Data Recovery Free, etc, could help. But, still do not whether it is necessary to have a try in my case. Do you have any idea? Much appreciated!

once you delete a folder from an SD card, you cannot keystroke it back. It's gone. You would need to put the card into a PC and use one of the apps you mentioned to try and recover the pictures.
