Exporting metadata to separated metadata files

[TaLL0s]

Hello,

I'm trying to do batch export of metadata from different directories with different files types to separated metadata files (for each graphics file one <full name graphics file with extension>.exf file with all available metadata from graphics file).

On the begining i have directory structure like this:

Code Select Expand


Katalog: C:\temp2\test files

2013-05-15  15:35    <DIR>          .
2013-05-15  15:35    <DIR>          ..
2013-05-15  15:41    <DIR>          DjVu
2013-05-15  15:41    <DIR>          Internetowe
2013-05-15  15:42    <DIR>          Merytoryczne
2013-05-15  15:42    <DIR>          Referencyjne
2013-05-15  15:42    <DIR>          TIFF_Druk

In each directory i have some specific files:
Katalog: C:\temp2\test files

DjVu - djvu files
Internetowe - small jpg's - Thumbnail
Merytoryczne - big jpg's
Referencyjne - source files (dng, cr2 with xmp, fff, tif)
TIFF_Druk - tif's

In that case i'm trying to use for each directory:

Code Select Expand

for /F %i in ( 'dir /B *') do exiftool -lang pl %i > %i.exf
Problem is that this method is not effective and generating those *.exf files takes too much time (1-2 seconds per file, because for each file i have to run program, read metadata, save it and close the program).

Is there any other way to generate those files with more efficent way (I have 20 000+ files in each directory)?

My example of generated files:

Code Select Expand


Katalog: C:\temp2\test files\Merytoryczne

2013-05-28  11:58    <DIR>          .
2013-05-28  11:58    <DIR>          ..

2013-02-13  20:38        15 805 996 MHK-Fs982-IX.jpg
2013-05-15  15:37             7 685 MHK-Fs982-IX.jpg.exf
               6 plik(ów)         46 096 538 bajtów
               2 katalog(ów)  34 560 020 480 bajtów wolnych
