What is the OPC file format?
A file with the .OPC extension is a file known as Microsoft Office 97 Upgrade Control. This format is associated with Microsoft Corporation.
The reliable way to open a .OPC file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .OPC files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
