How to open IDX255 file?

An often recurring problem with Runescape Cache Format is that IDX255 is not associated with the correct program file. This is manifested by the fact that IDX255 files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the IDX255 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. To do this, enter the name Runescape 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 is a list of programs that support the file IDX255.

Programs to open IDX255 file

Remember to download programs supporting IDX255 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Runescape with IDX255 files

If, despite the installed application, the IDX255 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. 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. Checking the "Always use the selected program ..." box will permanently associate the IDX255 file with the Runescape program.

Step 3. Update Runescape to the latest version

If, however, after binding Runescape with Runescape Cache Format 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 Jagex Ltd. website and install the latest version.

Step 4. Check for the following problems with the IDX255 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:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the IDX255 file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. 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 IDX255 file that we want to open. However, remember that not every infected IDX255 file can be recovered, so it is important to take care of regular backups.
Older version of IDX255 file may not always be supported by the latest software version. 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.
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 option of recovering data from damaged IDX255 files. You can restore the file from a backup or use Jagex help.
The program can also signal the fact of encryption. The encrypted file IDX255 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 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 IDX255 to a different directory.
This problem only occurs with 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 IDX255 to close. However, some background programs may block the IDX255 file while scanning. If this does not work either, restart the device.
