How do you import and export zip

So originally it was that the export function above was generating a zip file, not a .dtable file..

A few of my bases are around 3gb so the UI would not allow me to download them. I modified the dtable_web_settings.pyDTABLE_EXPORT_MAX_SIZE to be 100gb so that solved that issue..

The issue I have now is I can not upload the .dtable files as they are too large. I need to find the system variable to increase upload size.

Is this related?? Increasing the file upload limit

If so how can i restore a base form a .dtable files that is over 2gb in size?
