Prevent Export Crashes: Warn users before export if the target disk has insufficient space (Fix Error Code 39)

Currently, Premiere Pro displays an "Estimated File Size" in the Export window, meaning the software is fully aware of the projected file size and the destination path. However, it does not cross-reference this data with the actual available space on the target drive before starting the render.

Recently, during a long 1.5-hour documentary export, my export crashed on the very last frame, throwing a generic, misleading "Error Code 39 / Selector 9 (Component: H.264 of type Exporter)". After hours of troubleshooting effects and source clips, the actual culprit turned out to be a full destination disk.

The Request: Please implement a simple pre-flight check in the Export workflow. If the available space on the selected drive is less than the Estimated File Size (or within a 15-20% safety margin), Premiere Pro should pop up a clear warning BEFORE processing: "Warning: The destination drive may not have enough space to complete this export. Please free up space or choose a different drive."

Furthermore, if an export fails due to a full disk mid-way, the error code should explicitly state "Disk Full" instead of crashing with a generic encoding/frame error. This would save editors hours of needless troubleshooting.
