Hi! Sadly with the other part I stucked without any clue. From the jobs (jenkins/war/work/job/ExampleName ) I see this example:
<folderViews class="com.cloudbees.hudson.plugins.folder.views.DefaultFolderViewHolder">
<views>
<hudson.model.AllView>
<owner class="com.cloudbees.hudson.plugins.folder.Folder" reference="../../../.."/>
<name>All</name>
<filterExecutors>false</filterExecutors>
<filterQueue>false</filterQueue>
<properties class="hudson.model.View$PropertyList"/>
</hudson.model.AllView>
When I change it manually ,I see the change. But as this is generated, change needs to be happen somewhere else. I found this similar example in work\config.xml:
<hudson.model.AllView>
<owner class="hudson" reference="../../.."/>
<name>all</name>
<filterExecutors>false</filterExecutors>
<filterQueue>false</filterQueue>
<properties class="hudson.model.View$PropertyList"/>
</hudson.model.AllView>
This is where other part of the Jenkins correctly converted All -> Tous . In this scenario the src/main/resources/hudson/model/Messages_fr.properties file used
Hudson.ViewName=Tous
In javadoc I see that Hudson has this key value : 
But in the Folder plugin Doc I did not find this Key option and my knowledge is very limited to understand how to implement it to the plugin.
In AllView change did not help, I tried other property files in the plugin&core but none of them changed the value. Any new idea welcome.
Hi!
I found the "This folder is empty" part in the code: core/src/main/resources/hudson/model/AllView/noJob_fr.properties
As this language translation handled by properties files nearly all languages missing this sentence (but Turkish) All of this noJob_xx.properties files need the
This\ folder\ is\ empty=<sentence in the other language> line.
What is the correct way to handle it?
