I have noticed this problem for a long time and have always manually fixed it. I finally had enough of it last night after manually deleting 3,000+ duplicated pictures on my PC.
I sync all my media between my device and Desktop Manager, 7.1.0.32, and all my device pictures are multiplied on my PC. For example: IMG-001 multiplies to IMG-001_2, IMG-001_3, IMG-001_4 and so on.
The photos on my device are fine, it is the photos on my PC, C:\Users\Pictures\BlackBerry, that are the problem.
Anyone else have this problem?
This has happened on all DM versions that I can remember.
