Keeping integrity of data/coordinates when exporting from SHP to TAB and viceversa

Hi,
I happen to have a recurrent issue when opening/exporting vector files.
I have found out when exporting SHP to TAB and viceversa the coordinates are rounded, How can I keep the exact geometry at all levels (the exact same geometry) irrespective the format?

Thanks in advance!

Hello Alberto,
Unfortunately, this is an inherent limitation of the TAB format. Coordinate values are not stored in their full resolution. If you start with a TAB file, converting to SHP should work because SHP can match the resolution of the TAB file. However, if you start with a SHP file, you will lose resolution when you export to TAB.
