How to open IDX0 file?

The most common problem when using Runescape Cache Index Format is that a specific IDX0 is not associated with the program. This is manifested by the fact that IDX0 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 IDX0 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 Runescape

In this case, you should first verify that the Runescape application is installed on the computer. This can be achieved by typing Runescape into the operating system search engine. 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 IDX0.

Programs to open IDX0 file

Remember to download programs supporting IDX0 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Runescape with IDX0 files

If, despite the installed application, the IDX0 file does not start in the Runescape application, you must create a file association. 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. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the IDX0 file with the Runescape application.

Step 3. Update Runescape to the latest version

The fault may also lie with the Runescape program, it is possible that Runescape Cache Index Format requires a newer version of the program. In this case, use the Jagex Ltd. website or update the program from the application.

Step 4. Check for the following problems with the IDX0 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 IDX0 file may be unusually small compared to the original file. Usually this applies to IDX0 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. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the IDX0 file that we want to open. As a result of the scan, sometimes it is not possible to recover IDX0 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the IDX0 files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular IDX0 file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Jagex
The program can also signal the fact of encryption. The encrypted IDX0 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. If possible, you can try to move the IDX0 file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the IDX0 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.
