What is 477 file?

How to open 477 file?

The most common problem when using MNS Shape Definition Companion Format is that a specific 477 is not associated with the program. Thus, when you open 477, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the 477 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 Master Navigator

An often overlooked issue is to make sure that Master Navigator is installed on the computer. To do this, enter the name Master Navigator into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file 477.

Programs to open 477 file

Remember to download programs supporting 477 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Master Navigator with 477 files

If, despite the installed application, the 477 file does not start in the Master Navigator application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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. Checking the "Always use the selected program ..." box will permanently associate the 477 file with the Master Navigator program.

Step 3. Update Master Navigator to the latest version

If, despite the association of the Master Navigator program with the MNS Shape Definition Companion Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the 477 file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The 477 file may be unusually small compared to the original file. Usually this applies to 477 files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our 477 file. As a result of the scan, sometimes it is not possible to recover 477 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 477 files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair 477 file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file 477 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 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. It is best to move 477 to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the 477 file for a certain period of time. If the problem persists, restart the machine.
