Notes about the SESTYLES 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 SESTYLES file type is primarily associated with 'Spatial Workshop' by Spatial Eye. Spatial Workshop gives access to stored geographical information and combines this data with business information and background maps. Data from different sources are combined within Spatial Workshop into business objects, which may be configured by the user.
