Does writing back decrease the used memory?

[sinus]

Hi Mario
I forgot to ask a question depending the RAM, what IMatch does use:

I have roughly about 50.000 nefs without writing back - data, means without a xmp-file.

If I would write back these nefs, means creating a xmp, would this somehow have a effect on the RAM? If yes, I would let create these xmps.

I don't understand.

You can always see how much memory IMatch uses in the Windows Task Manager. IMatch also reports this in the log file (search for the word PEAK).

Whether NEF files have XMP files or not does not really matter. Most memory in IMatch is consumed for caching database objects, especially categories. Metadata extracted from files is stored in the database. IMatch only caches metadata from frequently or recently accessed files in memory, but that's only a few MB.

Thanks, Mario, you have answered my question perfectly with the sentences above.

Sorry, that I was not very clear. The background from my question was:
If I take 100 nefs with my camera, then usually I edit only say 30 images. These 30 images have of course xmp, because I do edit them in Photoshop (raw).
The other 70 nefs I do not edit, and hence let them without a xmp-file, all metadatas are therefore only in the DB, because I do not let write back these files.

So I thought, maybe I could save some memory, if I let write back these 70 files and let create xmp-files.
But your answer teached me, that this would not help a lot, because IMatch does only use the rececently used files and so on.

So everyhing is now clear for me, thanks a lot.
