Hello,

I want to set the cache directory because i cannot use AppData/Local/Temp/ for a certain reason. I'm using URLClassLoader, and i want it to temporarily save in another folder instead of AppData/Local/Temp/. How can i do this?

Please help,
Thanks Dunnkers.

You need to change the Java Runtime's tmpdir property. You can do that like so:

java -Djava.io.tmpdir=C:\my\file\location MyProgram

See if that works, since I believe URLClassLoader just saves temp data to the folder on that property.

How can i change this when in java? In my code itself? Also, i cannot use exec.

I haven't tested it, but I'd use System.setProperty:

String propertyName = "java.io.tmpdir";

String oldLocation = System.getProperty(propertyName);

System.setProperty(propertyName, "/location/of/file");


// Do your other stuff here.


System.setProperty(propertyName, oldLocation);
