Save only modified files

If this check box is selected, only the modified files are saved to PLM when you perform the Save to PLM operation.

The Save only modified files preference is applicable only for Save to PLM operation and is not applicable for Save and Unlock and Check-In operations. The reason being that if the files contain mapping, then even if the files are unchanged, still the Save and Unlock and the Check-In operations might modify the files as a result of the mapping definitions.
