What is JJ file?
The file in the JJ format belongs to the Graphic Files category. In addition to this file, the Graphic Files category includes 524 related files. Doodle C64 Compressed Image Format appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The XnView application is recommended to open the file. It was released by Pierre-Emmanuel Gougelet.
How to open JJ file?
The main problem with Doodle C64 Compressed Image Format is that the JJ file is incorrectly associated with programs. This is manifested by the fact that JJ 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 JJ 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 XnView
The first step is to check if the computer has the XnView program installed. This can be achieved by typing XnView 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 JJ files.
Programs to open JJ file
Remember to download programs supporting JJ files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of XnView with JJ files
If the application is or has been freshly installed, but the JJ file still does not use the XnView 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. Using the "Change" button we can set the program to handle this type. 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 XnView application as the default for handling the JJ file.
Step 3. Update XnView to the latest version
If, despite the association of the XnView program with the Doodle C64 Compressed Image Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Pierre-Emmanuel Gougelet website or update the program from the application.
Step 4. Check for the following problems with the JJ file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
The JJ file may be unusually small compared to the original file. This suggests truncating the JJ file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file JJ or the program directory. Sometimes virus-infected JJ files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the JJ files changes over time. 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 JJ file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted file JJ 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 JJ 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. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file JJ to close. 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.
