Dynamic workArea

Hi everyone, I’m having a problem. I’m launching several Knime processes in batches. Each process, using the preferences, writes to a workArea in this path: /instance/org.knime.workbench.core/knime.tempDir=\\MKSAS\\DT\\WorkArea Unfortunately, this process is very slow to delete in some cases. Do you think it’s possible to create dynamic workAreas based on the workbench file name and speed up the deletion of existing files?
If it helps you, the launch is done via a batch script like this
%Knime_path%knime.exe -application org.knime.product.KNIME_BATCH_APPLICATION ^
--launcher.suppressErrors ^
-nosplash %save% ^
-reset ^
-updateLinks ^
-preferences=%preferences_path% ^
-workflowFile=%workflow_file%^
%credentials% ^
-data %work_path%\workspace ^
-destFile=%last_file%^
-workflow.variable=DATA_BATCH,%DATA_BATCH%,String ^
-configuration %configuration% ^
%params% ^
%launcherPath%

Thank you very much.
