XnView Software

Your catalog (xnview.db) was created and updated (add categories etc ..) with a unique version of XnViewMP ?
I think I read that xnviewMP last version cannot use a previous version of catalog ...

Fr: Jusqu'en version 0.99.x , on pouvait utiliser le caractère \ (dans Windows) pour déplacer des fichiers dans des sous-dossiers.

Par exemple, avec des photos dont le nom commence par les 4 chiffres de l'année, ça permettait de répartir (trier) un ensemble de photos dans les dossiers annuels ...

En version 1.9.3, je n'ai pas réussi à réaliser un remplacement comme indiqué ici ...
ni avec {IPTC:Caption [~mot1~mot2]} ni avec {IPTC:Caption [s/mot1/mot2/]}

Six years later, I found the answer in this post
Thanks to Jkm ...

Instead of using $1,$2,$3... we must use \1 , \2 , \3

In my example : replace ^([0-9]{4} by \1 janvier

Perhaps you can use this name template in the first field :
{Modified Date [Y-m-d_HMS]}
or
{META:ModifyDate [Y-m-d_HMS]}
but timezone can be wrong ...

Depending on the video format, these metadata may be missing
So I recommend following Cday's advice !

Now, I understand why some strange folders appeared in my photos when using XnViewMP...
To delete a file or a folder whose name is incorrect, you can also use it's short name shown with dir /X command.

Surprenant ! Chez moi ça fonctionne ...
(XnViewMP V1.9.3 avec Windows 10 )

It seems that since adding the “Number of pages” icon or the second ‘Companion’ icon, my color image “info.png” no longer works very well.
At least a 12 x 12 pixel square must be added to the right.

Why two Companion icons ? (Compagnon pour la traduction en Français)

Sometimes, I change my keyword choices for sets of photos that I select. As mentioned in another thread, keywords previously used on some of the photos appear grayed out, while those that exist in all the photos in the selection have their checkbox checked. This allows me to view the indexing status ...

I think XnViewMP must read xmp data of each image before knowing if the update is necessary or not.
There is no guarantee that the catalog matches the photo data before running the operation.
This is precisely the way for the user to ensure that, after the operation, the catalog will be ...

Faites avant tout une copie de sauvegarde de votre fichier xnview.db , au cas ou il y aurait quelque chose à récupérer ...
Créez un fichier texte contenant un mot ...
Dans le panneau catégories, cliquez la flèche de menu déroulant
Cliquez Gestion des catégories, importer un fichier de catégories

With ExifTool (used in xnViewMP as an AddOn) , we can find in your photo :
1) IPTC:Keywords : Venice, La Biennale, VIP, culture, famous, celebrities, film, news, people, photo, entertainment
2) IPTC:Headline : 81nd Venice international film festival, Venice, Italy
3) IPTC:Caption-Abstract : Venice ...

Search on file names only ?
1) In displayed files : Quick search field in toolbar : aaa.*bbb|bbb.*aaa


2) In a folder and all subfolders ? Use Tools > search
Select the parent folder, and
- Search in catalog
- Search in subfolders
- Use Regular Expression
Enter aaa.*bbb|bbb.*aaa in "Filename" field ...

Or referring to : "File > Open with... > Configure" feature ?

see How to use ExifTool in XnViewMP
( but some things may have changed since i wrote this tuto )

but I don't recall any app that uses separate matching option at condition level

FastPhotoTagger (freeware .jar app) can work on any tag managed by ExifTool... even in it's DataBase, and queries can be built with "And" and "OR" for each tag
But it's not as convenient as Xnview
