Well folks thanks for the attention, but I thought somebody involved with the development could answer this.
I use a file name scheme like [prefix][Unique IDentifier]. 'Prefix' is one character:'d' for digital camera files, 'n' for scanned negative film, 's' for scanned slide film.
For digital camera files the UID is Date: yymmdd, '-' separator, and a sequence number. And the files are downloaded in folders by Date as well: D:/YYYY/YYYY-MM-DD (I use Windows)
I don't want this Sequence Number to be the one generated by the camera. If a picture is the 1''th picture taken at that particular date so the filename should be "dYYMMDD-1''.cr2", right?
LR gives me that. The problem is, when I use the token 'Sequence#()' I have to check all the time the start sequence number, or I'll have the first file of that day starting not as '''1' but lets say '746'. Or I have 2 "''1's", one '''1' and a '''1(2)' (what is a particular MS Windows silliness, I know).
A friend point me to the 'Image#()' token, that seems to work better for my purpose, but today I'd have a similar problem I had with 'Sequence#()'...
What i want is when downloading LR could figure out that if there is no file in the folder 2''8/2''8-11-'4 then the first file of the sequence should be '''1'. If there are files already in the folder then LR should pick the number of files already there and start the new sequence from there.
I'm sorry, I'm not sure if I'm been clear....
It seems I'll have to test it all anyway.
Thanks
