How to open KEYLIST file?

The most common problem when using UltraEdit Data Format is that a specific KEYLIST is not associated with the program. Thus, when you open KEYLIST, 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 KEYLIST 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 UltraEdit

An often overlooked issue is to make sure that UltraEdit is installed on the computer. This can be achieved by typing UltraEdit into the operating 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 KEYLIST files.

Programs to open KEYLIST file

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

Step 2. Create association of UltraEdit with KEYLIST files

However, it may happen that the application itself does not cause the KEYLIST file to open in the UltraEdit application, but you can set it manually. 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 UltraEdit application as the default for handling the KEYLIST file.

Step 3. Update UltraEdit to the latest version

If, however, after binding UltraEdit with UltraEdit Data Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the IDM Computer Solutions, Inc. website and install the latest version.

Step 4. Check for the following problems with the KEYLIST 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. Usually this applies to KEYLIST files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our KEYLIST file. However, remember that not every infected KEYLIST 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 KEYLIST files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular KEYLIST file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
When reading, a message appears that the file was encrypted or corrupted. The encrypted KEYLIST 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. These directories are write-protected to them and it's very hard to fix this problem. It is best to move KEYLIST to a different directory.
This can happen on a file that does not support multiple access. In this case, the KEYLIST file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the KEYLIST file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
