File renaming with unique identifier

[NicRacine]

Hi guys,

Using PM5 on Windows 10.

I am new to photo Mechanic, longtime Lightroom user, and I am trying to rename my files in the Ingest process. What I want to do is rename the first part of the file and keep the camera-assigned number.

For example, if my photo is named IMG_7201, I want to rename it SOMETHING_7201.

So I tried to use variables like this : fldr_fnm4, as fldr is the name of the folder on my DS card, and I thought fnm4 was the last four digits of the frame number (as stated in the wiki)

However, PH won't let me, stating that I need to use a unique identifyer.

What am I doing wrong?

Thanks in advance.

Hi NicRacine,

you had to use the variable {filebasename} with substring parameters. In you example use this rename rule:

SOMETHING_{filenamebase:4,4}.

You are telling PM to use the filename without extension (filenamebase), start to count, left to right, from first letter (that is 0 position) and take 4 chars.

You can also start to count from right to left using minus symbol: SOMETHING_{filenamebase:-4}. In this case the notation requires only one parameter.

Ciao,
A.

It's working, thanks!

I should not have skipped straight to the parameters definition. I've seen it in the Wiki now.
