What is MBS file?

The file in the MBS format belongs to the Misc Files category. It was designed by Opera Software. Additionally, the Misc Files category contains 6033 of other files. Opera Mailbox Format appears on 3 operating systems as a functional file. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. There are also 4 alternative programs to handle the MBS file. Aid4Mail, MBS2MBX will apply when it is not possible to use Opera.

How to open MBS file?

The main problem with Opera Mailbox Format is that the MBS file is incorrectly associated with programs. Thus, when you open MBS, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MBS 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 Opera

The first step is to check if the computer has the Opera program installed. To do this, enter the name Opera into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open MBS files.

Programs to open MBS file

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

Step 2. Create association of Opera with MBS files

If, despite the installed application, the MBS file does not start in the Opera 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. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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 Opera application as the default for handling the MBS file.

Step 3. Update Opera to the latest version

If, however, after binding Opera with Opera Mailbox Format there were still problems, you should update the program to the latest version.

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

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

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the MBS file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file MBS or the program directory. As a result of the scan, sometimes it is not possible to recover MBS 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 MBS 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MBS file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file MBS 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. If possible, you can try to move the MBS file to another location.
This can happen on a file that does not support multiple access. 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 MBS file again. However, some background programs may block the MBS file while scanning. If this does not work either, restart the device.
