Issue Description / Cause
Error Description
For very large projects processed on PIX4Dcloud, the results folder may not be available for download as a single ZIP file. In the Files > Results page, under the Export to PIX4Dmapper section, the following behavior may be observed:
-
The status shows an ERROR label.
-
The message Project is too big to zip is displayed.
-
The Download button is not available.

Cause
The PIX4Dcloud server is unable to compress the entire results folder into a single ZIP file due to its size. This is a technical limitation related to very large output datasets and does not indicate an issue with the project processing itself.
Possible Solutions / Checks
-
Download the output files individually instead of as a single ZIP archive.
For step-by-step instructions, see: How to download the results from the Cloud.
Downloading individual outputs allows access to all generated results even when the full project cannot be zipped for download.
