This is a very easy to use utility. Once the application is opened, simply select a date via the drop down menu at the top of the screen.
The date you select is the cut-off - no SMS text messages will be deleted after this date. To proceed and remove the messages from before that date, open the Menu and select Purge.
If you prefer to check what messages are going to be deleted however, select Load in the Menu first, and monitor and review your selection. This screen updates each time you make a change to the date.
Once Purge has been selected, the software asks for confirmation that you wish to delete the selected messages. It then disconnects your Windows Mobile device from your network - this is done to avoid new SMS messages being downloaded, an occurence that could damage the SMS database. After the purge is completed it is necessary to switch your phones data connection back on.
Finally, SMS Purger creates a log file with a copy of the deleted SMS messages within. This can be deleted if required, or saved to PC.
