After code runs:
DoCmd.TransferSpreadsheet acImport, , "Temptable1", FilePath, True, "Sheet1!A1:AX65000"
Access freezes and after 20 min exeption is throws because size of database grows from 15Mb to 2Gb.
I know the size limits of file. And seems that database grows because of error tables created. But why and how to stop it?
