NVIDIA FLARE maintains a workspace for keeping the FL apps and execution results for different jobs
under folders with the name of the job_id
.
The following is the workspace folder structure when running NVIDIA FLARE for the server and clients.

In each job_id
folder, there is the app_server
folder that contains the :ref:`application` that is running
on the server for this job_id
.
The log.txt
inside each job_id
folder are the loggings of this job.
While the log.txt
under server folder is the log for the server control process.
The startup
folder contains the config and the scripts to start the FL server program.
When the job is running, each job will have a corresponding workspace under the server
folder.
When the job is finished, the server side workspace will be removed. The workspace will be saved into the JobStorage.
You can issue the download_job [JOB_ID]
in the admin client to download the server side workspace.
The downloaded workspace will be in [DOWNLOAD_DIR]/[JOB_ID]/workspace/
.
Note
If you issue download_job
before the job is finished, the workspace folder will be empty.
