[Chris Evans]"What happens if you uncheck File Extension under Match File Properties?"
That should work.
If all else fails just export XML from Premiere.
Import into REDCINE and link the Master folder (R3Ds) and then force to open i Premiere (sorry forgot the actual menu name) or just export XML again and import into Premiere.
Ive had to do this a few times cause there is now way to find was is used in a project in Premiere (not that I know off).
Do an XML import into a new project and you notice that it only imports the files used.
