[PCI Discuss] File size when using FEXPORT?



Hi

Why do I get (480) extra bytes when exporting data using EASI/FEXPORT:

In the case below I export a file that is 5000 x 2500 x 2 bytes = 12,500,000 bytes
bur the resulting file is
12,500,480. What/where is the extra bytes?
How to get rid of these bytes?

Running 10.3.1 on XP
Regards

Jonas Ardö
