How to change the temporary directory used by CQ

These files are created when you are building/uploading packages on your installation.

You can either remove these files after the packages have been installed or run a cron job to clean these files.

Also, you can change the location of the temp directory by following the 2 ways:

The default location of the temporary folder of the java machine is /tmp. AEM uses this folder too, for example when building packages.

If you want to change the location of the temporary folder (for example, if you need a directory with more free space) then define a <new-tmp-path> by adding the JVM parameter:

-Djava.io.tmpdir="/<new-tmp-path>"

to either:

the server startup command line
the CQ_JVM_OPTS environment parameter in the serverctl or start script
