The origin and purpose of a .pthc file cannot be determined from the extension alone. No vendor, application, or platform association is established for this file type.
Its contents and current status are unknown. The file may belong to a private or specialized application, or the extension may have been assigned by a particular user or system.
There is no known dedicated program for opening a .pthc file. Identify the application or device that created the file before attempting to open it.
Do not rename the file to another extension unless its format is known, because changing the name does not convert its contents.
No reliable conversion method is available for the .pthc file type. Conversion depends on identifying the software that created the file and whether that software supports export to a documented format.
