In and effort to create a batch file version using TagsFromFile to copy a tag out to an xmp or mie file I have this :
exiftool -TagsFromFile %%f.nef -xmp-crs:all *.xmp
However, if an xmp file is not present it will not be created and I get 'file not found'. If it is present then the process works and the tag is copied out to the xmp and a copy created.
I'm trying to use TagsFromFile to create an MIE or xmp for all files at once rather than having to do them individually. Is it possible ?
