Welcome to Camera Bits Forums
this is when ingesting from a Lexar firewire reader from a Lexar 133x speed 4 gb card, nef and jpg files from a nikon d2x, doesnt happen every time but when it does it duplicated the previous file and adds an A into the filename.
No, I am not renaming
That has been the case on some occasions and of course then it will use the collision renmaning system but its also occured on first download to an empty folder.
