3742505 - MDF Attachment import via SFTP/Provisioning fails due to file type or size limit

• Importing MDF attachments via “import and export data” succeeds, but importing the same data via SFTP and Provisioning fails.
• Using file type “csv” for the MDF FTP job causes the import to fail (job expects a zip).
• Error observed for large files: NegativeArraySizeException: -808143088.
• Error indicates that when using FTP, the file size limit is 1 GB.
• Existing guidance consulted lacks detailed SFTP–Provisioning steps.

1. Import MDF attachment data via “Import and Export Data” successfully.
2. Configure and run an MDF Import via SFTP in Provisioning with an incorrect file type or a file larger than the allowed limit; the job fails.

• The MDF FTP job was configured with the wrong file type (csv instead of zip) and/or misconfigured for ZIP handling.
• The uploaded ZIP exceeded the MDF FTP job file size limit (1 GB), leading to failures; very large files can surface NegativeArraySizeException.

1. In Provisioning, configure the MDF Import FTP job to use ZIP format (ensure “zip” is selected and the job is set up for ZIP processing).
2. Package the import template (.csv) and the attachments folder inside a single .zip file.
3. Ensure each ZIP file is 1 GB or smaller; split large datasets into multiple ZIP archives below this limit.
4. Re-run the MDF Import FTP job for each ZIP; verify successful completion and imported attachments.
5. If NegativeArraySizeException occurs, reduce the file size further and retry.
