Notes about the ZTMP 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 ZTMP file type is primarily associated with 'Steam' by Valve Corporation. When a Steam client downloads a resource from a Steam game server (like a .BSD map), the resource is first compressed to save bandwidth. An associated .ZTMP file is stored on the server so the resource won't need to be compressed again the next time a client requests it. If you change the resource you need to delete the associated .ZTMP file so that the next person who downloads is doesn't get the old copy instead of the changed resource file (Steam does not detect changed game resource files and recreate the .ZTMP file automatically.)
