How to open ECF file?

An often recurring problem with Outlook Add-in is that ECF is not associated with the correct program file. This is manifested by the fact that ECF files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the ECF 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 Microsoft Outlook

The first step is to check if the computer has the Microsoft Outlook program installed. This can be achieved by typing Microsoft Outlook into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open ECF files.

Programs to open ECF file

Remember to download programs supporting ECF files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Outlook with ECF files

If, despite the installed application, the ECF file does not start in the Microsoft Outlook application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the ECF file with the Microsoft Outlook program.

Step 3. Update Microsoft Outlook to the latest version

If, despite the association of the Microsoft Outlook program with the Outlook Add-in file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the ECF file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the ECF file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our ECF file. However, remember that not every infected ECF file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the ECF files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair ECF file corruption. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted file ECF except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move ECF to a different directory.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the ECF file again. Some anti-virus or backup software may occupy the ECF file for a certain period of time. If the problem persists, restart the machine.
