I have opened a database (either Directly open Access/Excel, or via ODBC) table in MapInfo. I am trying to use File>Save Copy As and receiver the error -
"Cannot write database row. Possibly out of disk space. Operation cancelled."
Solution
The default native TAB file format has a limitation on the total byte size of the fields/columns added up, also the data file size could not exceeded 2GB.
A new version of the TA file was introduced that has no limit of the number of fields. This is called MapInfo Extended (*.tab). Change the file type in the save as dialog to MapInfo Extended to overcome the error.
See also the MapInfo KB article
Note that this type of TAB file is not supported in some Discover tools, and other 3rd party software.
