How to open QPL file?
An often recurring problem with KaleidaGraph Layout is that QPL is not associated with the correct program file. This is manifested by the fact that QPL 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 QPL 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 KaleidaGraph
In this case, you should first verify that the KaleidaGraph application is installed on the computer. This can be achieved by typing KaleidaGraph into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open QPL files.
Programs to open QPL file
Remember to download programs supporting QPL files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of KaleidaGraph with QPL files
However, it may happen that the application itself does not cause the QPL file to open in the KaleidaGraph application, but you can set it manually. 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. Using the "Change" button we can set the program to handle this type. 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 QPL file with the KaleidaGraph application.
Step 3. Update KaleidaGraph to the latest version
If, despite the association of the KaleidaGraph program with the KaleidaGraph Layout 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 Synergy Software website and install the latest version.
Step 4. Check for the following problems with the QPL file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
Very often, the file may be size 0 or incomplete. This suggests truncating the QPL 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 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 QPL or the program directory. However, remember that not every infected QPL file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the QPL file. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair QPL file corruption. The easiest way to restore the file is from a backup or by contacting Synergy Software, 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 file QPL except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
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. Copying the QPL file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the QPL 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.
