Possible problems with the EXTENSIONS/EFK format files
The inability to open and operate the EXTENSIONS/EFK file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the file. Below is a list of possible problems.
- Corruption of a EXTENSIONS/EFK file which is being opened
- Incorrect links to the EXTENSIONS/EFK file in registry entries.
- Accidental deletion of the description of the EXTENSIONS/EFK from the Windows registry
- Incomplete installation of an application that supports the EXTENSIONS/EFK format
- The EXTENSIONS/EFK file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the EXTENSIONS/EFK file.
- Drivers of equipment used by the computer to open a EXTENSIONS/EFK file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the EXTENSIONS/EFK file should operate with your programs without any problem. If the problem with the EXTENSIONS/EFK file has not been solved, it may be due to the fact that in this case there is also another rare problem with the EXTENSIONS/EFK file. In this case, the only you can do is to ask for assistance of a professional staff.
