Be careful not to rename the extension on .opf files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.what is a file extension?
A file extension is the set of three or four characters at the end of a filename; in this case, .opf. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.leave a comment
