The ZipStream Sync utility is used to wait for background compression operations to complete. When this utility is activated the background compression system will receive a large boost in priority so that all the outstanding compression operations will be completed in the shortest possible time.

If there are background compression operations, the utility will display a running counter, as shown above, until all background compression operations have been completed.
When all operations have been completed, the utility will display a message box, as shown below. Click on OK to terminate the utility.

This utility is most useful when files have been written to diskette and it is not known when all processing has been completed. When the utility displays its completion message box you will know it is then safe to remove the diskette from the diskette drive.
