I have a couple of .db backup Quickbooks POS files that I'm trying to import into Quickbooks POS version 9. Every time I try to either open, import or "convert from previous version" I get an error while its reading the file:
"Invalid size or check sum of file or unsupported compression format - Native error: 00008. File processing error, possibly disk is full"
Am I importing wrong? Is there a quickbooks repair tool that can find errors and fix the file?
