If you have modified any predefined Trimble files and saved them with the original name, then those files are replaced with new versions of the predefined files when you upgrade the software, and any custom changes are lost. In this case, you must manually copy the modified files from the local folder and copy them into the appropriate Trimble Data subfolder after the software upgrade. To avoid this, if you modify a predefined format then make sure you save it with a different name.
