Hi @julien1234
Yes, that is possible with
| App-Id | files_scripts |
| App-Name | File actions |
| Summary | Scripting tool which allows administrators to expand the file options menu. |
| Categories | files workflow |
| Repository | GitHub - Raudius/files_scripts: Custom file actions app for Nextcloud |
| Issue-Tracker | Issues · Raudius/files_scripts · GitHub |
| Admin-Doc. | files_scripts/docs/README.md at master · Raudius/files_scripts · GitHub |
| Not-shipped (not included) App available in appstore | |
| Appstore | https://apps.nextcloud.com/apps/files_scripts |
(It requires the php-lua extension, which is not provided by Ubuntu/Debian. You can use → php-module-builder ← for that.)
That app gives you the means to integrate lua code and can → tag files ←
It can be used with nextcloud flow. That means you can trigger every new added zipfile to be inspected for its content and depending on the result assign a tag.
The app only provides you with the frontend/interface. You have to write the Lua code (and possibly Bash, Perl or Python scripts to check the content) yourself. But this case is nothing particularly complicated.
Much and good luck,
