Playbook. How can I delete photo files?

I exported to my Playbook 3 files of photos to show on the TV. I now want to delet all 3 files but only seem able to delete photos by selecting each one then deleting. With over 200 photos in all this take some time. I am running OS 2.1.0.1917. I have read previous posts but none have covered this.

You can get a file manager (free) in app World to handle this. Just install, and you shall be able to multiple select files to delete. Look for "Ghost Commander"...

You can also delete by connecting your PlayBook via USB, and using the virtual network drive that the PlayBook maps to on your PC to delete them, especially if you transferred them as folders.

Thanks for the help. Not sure what virtual network drive is, Ive got Blackberry Desktop on my PC would have thought it could be done from there. Will download Ghost Commander and try that.
