How should I configure storage and temporary files for large projects?

Context

This article applies to performance and storage questions involving the temporary folder, limited disk space, NVMe storage, external drives, and large projects.

Resolution

Confirm that both the project drive and the Correlator3D temporary directory have enough free space for intermediate products. You can review or change the temporary location under File > General Settings.

For best single-station performance, place the temporary folder on a separate local drive from the input and output data. For distributed processing, share the main station's temporary folder and enter it as a network path that every processing station can access. For distributed workloads, the Correlator3D User Manual recommends PCIe NVMe storage and a 10 Gigabit network.

Before rerunning a failed job, record the free capacity on every involved volume. Verify that security software or automated cleanup policies are not removing temporary files during processing. Interrupted DSM pair files may be recoverable with the DEM Merging tool.

Limited storage is a performance concern and may affect processing reliability. Do not identify it as the cause of a specific crash unless the logs show an input/output, missing-file, or insufficient-space error.
