XnView Software

I use the batch converter to resize and move JPG files (and if needed convert to JPG)
If you take a graphic and add categories then use the batch converter, the categories are stripped when you chek them at the destination folder

categories written in embedded metadata?

I use the category feature in the program. I have created my own tre of categories
I add them to a graphic but when I use the batch converter to resize and move them, the categories are no longer there in the file

could you post a screenshot of Settings>Metadata?

IF I use the batch converter to resize only, the categories seem to stick. If I resize and move, the categories are gone
Here is a video

Xnviewmp updates the catalogue when moving files by drag and drop, or rename folders with the browser.

But I think that moving files using the trick of changing its folder name in a batch is perhaps not detected as a move ...
In this case, I update the catalog by deleting / importing folders (Settings, catalog ... )

but keywords are written in IPTC?

I add them as shown in the video ... in the categories feature
I THINK this is new behavior since 0.98.3. I used to set categories, move them with the batch converter then find them by category in the new folder

but i need to know if categories are written in IPTC/XMP embedded metadata

Here is the screenshot

I tried V 0.96 ... it's the same as V0.98.4

Set export option to write iptc and xmp keywords.
Add a category to photo1.jpg in Folder-A .
Use batch convert and define Folder-B for output, with preserve metadata. This batch will copy photo1.jpg to Folder-B

-IPTC and XMP Keywords are preserved in target folder, but categories wont follow photo1.jpg in FolderB .
I think the catalog won't be updated unless import option is enabled to make the keywords to be read (or other methods)
And I think that catalog will not be updated either, if you use "delete original" option, previous categories won't be removed.

A new option could be added : "Import destination folder to update catalog after conversion" (in Tools, Batch convert, Ouput tab)
( ... And "delete original" should always remove entries in the catalog)

The problem is : Should we expect XnViexmp to work like Picasa by constantly updating the catalog?
(Similar problem if you rename a category ... embedded keywords won't be updated.)

I decided to perform separate tasks:
Move, backup, update, add or rename photos is a first task
Work with keywords / categories and update catalog is another task .

The setting 'Import XMP subject...' is not enabled so there is no import of metadata of new files

I just added the suggestions and no difference
It used to work correctly. I would edit the photos, add the categories then resize and move them with the batch updater. When I checked them in the receiving folder, the categories were still there.
Here are my settings changes that do not seem to work

could you send me input and output files?

Here are two of them that I use a lot. The resize then move to a folder. Add some categories to your test files then run these
You don't have to "move" it, just the resize will strip your categories. This is new behavior
Thanks in advance
