What is BUL file?

The file with the extension BUL is the Misc Files file type. The author of this format is The NSR Physiome Project. Misc Files consists of 6033 similar files. Bullseye Data Format appears on 1 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. It is recommended to use JSim to handle this file. This is a program created by The NSR Physiome Project.

How to open BUL file?

The main problem with Bullseye Data Format is that the BUL file is incorrectly associated with programs. Thus, when you open BUL, 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 BUL 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 JSim

The first step is to check if the computer has the JSim program installed. This can be achieved by typing JSim into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file BUL with JSim. Later in this article you will find a list of programs that can open BUL files.

Programs to open BUL file

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

Step 2. Create association of JSim with BUL files

However, it may happen that the application itself does not cause the BUL file to open in the JSim application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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 JSim application as the default for handling the BUL file.

Step 3. Update JSim to the latest version

If, despite the association of the JSim program with the Bullseye Data Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the The NSR Physiome Project website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The BUL file may be unusually small compared to the original file. This suggests truncating the BUL 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. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file BUL or the program directory. However, remember that not every infected BUL file can be recovered, so it is important to take care of regular backups.
Older version of BUL file may not always be supported by the latest software version. 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair BUL file corruption. The easiest way to restore the file is from a backup or by contacting The NSR Physiome Project, 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 BUL 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the BUL file to another location.
This can happen on a file that does not support multiple access. In this case, the BUL file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the BUL file while scanning. If nothing helps, please reset the device.
