Hi Support, I just like to report about an error I just encountered while trying to import a quite large .collect-data file into another instance of Collect. My survey has >1300 plots, each with a single foto of ~3MB, which makes the .collect-data archive > 4.4 GB. Importing this file leads to a Java error (CEP error "bad signature"). My first assumption was that the survey is not matching, but it seems to be a problem with file size. Exporting the data without fotos (~6MB) and importing is working fine. Lutz

Accepted answer

We finally solved this problem by excluding the images from the export and downloaded them manually from the tablets.
