Adding metadata shouldn't duplicate raw files without user consent

[Gwenael Q.]

Hello,

In continuation of viewtopic.php?f=62&t=44410&p=182744.

- Select some raw files,
- open "Edit IPTC" ("XMP, update or create IPTC-IIM" mode selected, not tried with another setting)
- Add keywords with keywords tab.
- Apply

What is observed:

- process is long to end...
- Each NEF (but probably same behaviour with other Raws) is duplicated (open folder in explorer to see the duplicates). Duplicate name is Filename.NEF_original

What should be observed:

No duplicate should be created unless a setting allowing for that is checked. Major drawback of raw files is the space they occupy in disks, if they get duplicated things will be even worse....

Seems to me that these duplicates are created because XnViewMP directly write metadata inside RAW files and the duplicates are backups....

I am very happy to know that XnviewMP allows editing of "embedded" metadata within RAWs. I used this kind of feature during a long time with an other software without never having problems, and I miss this feature. What surprises me is that I don't remember having seen any setting asking for user preference:

- RAW embedded metadata or XMP sidecar ?
- If raw embedded metadata then backup duplicate ?

Thanks for listening

so backup is created when changing metadata (Make backup for other lossless operations)

[Gwenael Q.]

Hello,

Indeed. If "Make backup for other lossless operations" is no checked then no duplicates are created !

Furthemore I confirm that with "Edit IPTC", metadata is embedded into Nef file, which leads me to open another post: viewtopic.php?f=60&t=44469&p=183109.

MP1.4.0 win 11.

Thanks for listening !
