Batch copying a tag to the corresponding file in another tree

[ericj]

Batch copying a tag to the corresponding file in another tree - sounds easy:

cd destination
exiftool -r -P -tagsfromfile source/%d%f.%e -subject .

... except that the files in source may or may not have the same extension as in destination (name is always the same). I can script this, but it will be slow, so is there a trick I have missed?

thanx,

eric

Hi Eric,

Well, there is a trick that you might be able to use.  If you know the possible extensions beforehand, you can add -tagsfromfile options for each one.  For example:

exiftool -r -P -tagsfromfile source/%d%f.jpg -subject -tagsfromfile source/%d%f.tiff -subject -tagsfromfile source/%d%f.nef -subject .

You will get warnings for the source files that don't exist, but the target file should get updated as long as one of the source files exists.

Thanks Phil, that seems to work, and I do know what the possible extensions are.
