What is MEF file?
The file in the MEF format belongs to the Data Files category. The creator of this file is Mamiya. In addition to this file, the Data Files category includes 1326 related files. Mamiya RAW Image is supported by 3 operating systems. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. The main program that supports this format is Adobe Photoshop Elements. This was created by Adobe Systems Incorporated. Alternatively, you can use 9 other programs. You can use ACDSee, PaintShop Pro, Helicon Filter, Picture Information Extractor in case Adobe Photoshop Elements cannot be used.
How to open MEF file?
An often recurring problem with Mamiya RAW Image is that MEF is not associated with the correct program file. Thus, when you open MEF, the program selection wizard or some other program starts. How to solve such a problem?
The first thing you should do is just "doubleclick" on the MEF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Adobe Photoshop Elements
The first step is to check if the computer has the Adobe Photoshop Elements program installed. To do this, enter the name Adobe Photoshop Elements into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file MEF with Adobe Photoshop Elements. Later in this article you will find a list of programs that can open MEF files.
Programs to open MEF file
Remember to download programs supporting MEF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Adobe Photoshop Elements with MEF files
If the application is or has been freshly installed, but the MEF file still does not use the Adobe Photoshop Elements program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Adobe Photoshop Elements application as the default for handling the MEF file.
Step 3. Update Adobe Photoshop Elements to the latest version
If, however, after binding Adobe Photoshop Elements with Mamiya RAW Image there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Adobe Systems Incorporated page and install.
Step 4. Check for the following problems with the MEF file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the MEF file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file MEF or the program directory. As a result of the scan, sometimes it is not possible to recover MEF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the MEF files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged MEF files. The easiest way to restore the file is from a backup or by contacting Mamiya, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted MEF files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the MEF file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the MEF file again. However, some background programs may block the MEF file while scanning. If this does not work either, restart the device.
