Notes about the ZTR file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The ZTR file type is primarily associated with 'Tracker' by SymbianWare OHG. Desktop skin for the Sony Ericsson P800 and Sony Ericsson P900.
