Tips to open UML file
Can't open the UML file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open UML files as well as a list of programs that support UML files.
UML file extension
The UML file is supported on 3 operating systems. Depending on your operating system, you may need different software to handle the UML files. Below is a summary of the number of programs that support and open the UML file on each system platform.
What is UML file?
The file in the UML format belongs to the Developer Files category. In addition to this file, the Developer Files category includes 1205 related files. UML Data Object Model appears on 3 operating systems as a functional file. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. It is recommended to use MagicDraw to handle this file. This is a program created by No Magic, Inc.. This file type can also be opened by 6 other programs. You can use Eclipse, Visual UML in case MagicDraw cannot be used.
How to open UML file?
The main problem with UML Data Object Model is that the UML file is incorrectly associated with programs. This causes the file UML to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the UML 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 MagicDraw
An often overlooked issue is to make sure that MagicDraw is installed on the computer. This can be achieved by typing MagicDraw 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. Below is a list of programs that support the file UML.
Programs to open UML file
Remember to download programs supporting UML files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of MagicDraw with UML files
If, despite the installed application, the UML file does not start in the MagicDraw application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. 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 MagicDraw application as the default for handling the UML file.
Step 3. Update MagicDraw to the latest version
If, despite the association of the MagicDraw program with the UML Data Object Model file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the No Magic, Inc. website or update the program from the application.
Step 4. Check for the following problems with the UML file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
The UML file may be unusually small compared to the original file. This suggests truncating the UML file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. 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 UML file that we want to open. Sometimes virus-infected UML files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the UML file. 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. Some programs offer the option of recovering data from damaged UML files. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted UML 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. It is best to move UML to a different directory.
This problem only occurs with more complex files. In this case, the UML file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the UML file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
