CEP: set/read scratch paths on/from project

Thanks for your reply!

I wrote a small script to show, what we're trying to describe:

function printAutoSavePaths() {
$.writeln("printAutoSavePaths()");
var projects = app.projects;
var foundProjects = [];
for (var i=0; i < projects.numProjects; i++) {
var project = projects[i];
$.writeln("[Project:" + project.name + "]" + "[AutoSave:" + app.properties.getProperty('BE.Prefs.ScratchDisks.FirstAutoSaveFolder') + "]");
}
$.writeln("");
return foundProjects;
}

var documentPath1 = 'C:\\temp\\1.prproj'
app.openDocument(documentPath1, true, true, true, false);
app.project.setScratchDiskPath('c:\\default\\1', 'BE::kPrefsScratchDisksFirstAutoSaveFolder');
app.project.save();
printAutoSavePaths();

var documentPath2 = 'C:\\temp\\2.prproj'
app.openDocument(documentPath2, true, true, true, false);
app.project.setScratchDiskPath('c:\\default\\2', 'BE::kPrefsScratchDisksFirstAutoSaveFolder');
app.project.save();
printAutoSavePaths();

Could you run the script above and check the Auto-Save Scratch-Disk settings under "File -> Project Settings... -> Scratch Disks..."?
(Tested with PPRO 23.4.0. Precondition: save file 1.prproj and 2.prproj to C:\temp)

The output should be somethin like this:

printAutoSavePaths()
[Project:1.prproj][AutoSave:c:\default\1]

printAutoSavePaths()
[Project:2.prproj][AutoSave:c:\default\2]
[Project:1.prproj][AutoSave:c:\default\2]

Ergebnis: undefined

So, how can we get the Scratch Disk Information from project 1.prproj then?

Quick test looks like the provided example does return the project-level auto-save folder.

app.properties.getProperty('BE.Prefs.ScratchDisks.FirstAutoSaveFolder');

Can you provide some screenshots if that's not what you're experiencing?
