PADS I/O Designer checks for updated files at a specified time interval, and prompts you to run Synchronization if it finds them. By default, this check is performed every 3 seconds, but you can change this time interval on the Setup > Settings + Synchronization Check page.
PADS I/O Designer tracks only the files selected in the Track Status column of the Synchronization Wizard in this check. Select the checkbox in the Track Status column for each item you want to check with the Synchronization checker.
Click Apply to save the Synchronization Wizard settings (tracking) for the current database. The settings are stored in the database file following a Save action.
