How to open QPJ file?
The main problem with Quantum GIS Project is that the QPJ file is incorrectly associated with programs. This causes the file QPJ 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 QPJ 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 Quantum GIS
The first step is to check if the computer has the Quantum GIS program installed. To do this, enter the name Quantum GIS into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support QPJ files.
Programs to open QPJ file
Remember to download programs supporting QPJ files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Quantum GIS with QPJ files
If the application is or has been freshly installed, but the QPJ file still does not use the Quantum GIS program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. 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 QPJ file with the Quantum GIS application.
Step 3. Update Quantum GIS to the latest version
If, however, after binding Quantum GIS with Quantum GIS Project 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 Quantim GIS project team website and install the latest version.
Step 4. Check for the following problems with the QPJ file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
The affected file may be 0 KB or smaller than expected. Usually this applies to QPJ files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the QPJ file that we want to open. Sometimes virus-infected QPJ files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the QPJ 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. Sometimes the program itself has options to repair the most popular QPJ file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Quantim GIS project team
When reading, a message appears that the file was encrypted or corrupted. The encrypted QPJ 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move QPJ to a different directory.
This problem only occurs with more complex files. In this case, the QPJ 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 QPJ file while scanning. If nothing helps, please reset the device.
