Hello

With XnViewMP 1.4.2 (on windows 11), I have a problem similar to the description of that post.


Settings/General/File operations

• Make backup for lossless flip/rotation : not checked

• Make backup for lossless crop : not checked

• Make backup for other lossless operations : not checked

Settings/Metadata

• Export catalog's category to XMP subjetct and IPTC Keywords : Checked
  • Create XMP data : Checked
  • Create IPTC data : Checked

• Automatically apply parent category : Checked

Description of the problem
The problem occurs when I add or remove category (and so XMP et IPTC data) to an important quantity of pictures.

• I use "Categories Filter" pannel and I display all pictures that have the category "Toto" : 4000 pictures.

• I select 1 picture and I remove "Toto" Category with Categories Pannel => No .bak file => OK for me

• I select 14 pictures and I remove "Toto" Category with Categories Pannel => No .bak file => OK for me

• I select 300 pictures and I remove "Toto" Category with Categories Pannel => 1 .bak file created => I dont' understand

• I select 2300 pictures and I remove "Toto" Category with Categories Pannel => 116 .bak files created (>600 Mo) => I dont' understand

• etc ...

Another problem :

• I use "Categories Filter" pannel and I display all pictures that have the category "Blabla" : more than 6000 pictures.

• I select all the pictures (CTRL+A) and I remove "Blabla" Category with Categories Pannel (it creates a lot of .bak files as described previously)

• In the "Categories Filter" pannel XnViewMP indicates that 0 picture still have "Blabla" Category

• I clean and rebuild my catalog (Settings/Catalog/Delete all + Optimize + OK + Close XnViewMP + Open XnViewMP + Settings/Catalog/Import Folder ...)

• In the "Categories Filter" pannel XnViewMP indicates that several hundreds pictures still have the categorie "Blabla" => It seems to miss some category removing when doing it on an important number of pictures.

files are jpeg? you can only reproduce on large list?

[malletp]

All my files are jpg.

For the moment I only observe this problem when I work on large list (more than 200) but for me it is the case most of time.
When I try with small number of pictures it seems to be OK for the moment.

files are jpeg? you can only reproduce on large list?

I've just done the same kind of actions with 114 pictures and XnView create 1 file with extension .bak (XnViewMP 1.4.3).

[xnview]

i've tried with 3000 files but can't reproduce. All files are in the same folder? You click outside thumbnails to apply category changes?

[malletp]

i've tried with 3000 files but can't reproduce. All files are in the same folder?

In all my previous messages, files were not in the same folder but they were displayed together as result of a research.
After your message, I tried to affect a category to 3000 pictures in the same folder and it creates 173 files with .bak extension.

You click outside thumbnails to apply category changes?

Yes. I select all thumbnails, I apply the category by clicking in Categories Panel, then I click outside thumbnails to apply category changes (and IPTC/XMP export in my case).

I don't know how to be more precise because it is very easy to reproduce for me: files .bak are created all the time
Maybe something is wrong in my settings but I don't see what.

[xnview]

please send me your xnview.ini?

Hello

I reopen this old post because I encounter the same case on a specific file.

I am using XnView Mp 1.8.6 with Windows 10

The case
Setings
-Import meta : off
-Export meta : on
-Sidecar : off
-Lossless operations : NoBackup

Actions
1 Select the file "Clan Renaud 20020824.jpg"
2 Check a category
3 Un-select the file

Result
-The category is assigned and saved in the file
-Creation of file "Clan Renaud 20020824.jpg.bak

Comments
This behavior is specific to the attached file and can be repeated. It is a small file 353Kb.


I have the same result with 1.8.1 and 1.8.5

I hope this case can help to make XnView even better

[jlrjlr]

I answer to my previous post:

The cause is that the file is "read only"

XnView reaction is a bit surprising since the changed category has been written into the "read-only" file
but once you know..

ps How can I remove the photo of my original post.
