How to open BU file?

An often recurring problem with Pegasus Mail Temporary is that BU is not associated with the correct program file. This is manifested by the fact that BU files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the BU 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 Pegasus Mail

In this case, you should first verify that the Pegasus Mail application is installed on the computer. To do this, enter the name Pegasus Mail into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support BU files.

Programs to open BU file

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

Step 2. Create association of Pegasus Mail with BU files

If, despite the installed application, the BU file does not start in the Pegasus Mail 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. 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 Pegasus Mail application as the default for handling the BU file.

Step 3. Update Pegasus Mail to the latest version

If, despite the association of the Pegasus Mail program with the Pegasus Mail Temporary file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the David Harris website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the BU file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the BU file that we want to open. Sometimes virus-infected BU files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the BU 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 the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged BU files. The easiest way to restore the file is from a backup or by contacting David Harris, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted BU 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. The problem is only writing to the file, not reading it. If possible, you can try to move the BU 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 BU file again. Some anti-virus or backup software may occupy the BU file for a certain period of time. If this does not work either, restart the device.
