The PU file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the PU files. Below is a summary of the number of programs that support and open the PU file on each system platform.
What is PU file?
The PU file has been categorized as Misc Files. The creator of this file is SourceForge.net. Misc Files consists of 6033 similar files. PlantUML is most often found on 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The main program that supports this format is PlantUML. This was created by SourceForge.net.
How to open PU file?
An often recurring problem with PlantUML is that PU is not associated with the correct program file. This is manifested by the fact that PU files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the PU 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 PlantUML
The first step is to check if the computer has the PlantUML program installed. The easiest method is to use the system search engine by entering the program name PlantUML in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file PU.
Programs to open PU file
Remember to download programs supporting PU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of PlantUML with PU files
If the application is or has been freshly installed, but the PU file still does not use the PlantUML program, it means no 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. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the PU file with the PlantUML application.
Step 3. Update PlantUML to the latest version
If, however, after binding PlantUML with PlantUML there were still problems, you should update the program to the latest version. In this case, use the SourceForge.net website or update the program from the application.
Step 4. Check for the following problems with the PU 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:
Very often, the file may be size 0 or incomplete. This suggests truncating the PU file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
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. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file PU or the program directory. Sometimes virus-infected PU files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the PU file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair PU file corruption. The easiest way to restore the file is from a backup or by contacting SourceForge.net, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted PU files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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 PU to a different directory.
This problem usually affects more complex files. In this case, the PU file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file PU to close. 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.
