How to open RNC file?

The most common problem when using RELAX NG Compact Syntax Format is that a specific RNC is not associated with the program. This causes the file RNC to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the RNC 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 Text editor

In this case, you should first verify that the Text editor application is installed on the computer. To do this, enter the name Text editor 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 RNC files.

Programs to open RNC file

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

Step 2. Create association of Text editor with RNC files

If, despite the installed application, the RNC file does not start in the Text editor 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. 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. Checking the "Always use the selected program ..." box will permanently associate the RNC file with the Text editor program.

Step 3. Update Text editor to the latest version

If, however, after binding Text editor with RELAX NG Compact Syntax Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the RNC file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The RNC file may be unusually small compared to the original file. This suggests truncating the RNC file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the RNC file that we want to open. Sometimes virus-infected RNC 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 RNC files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing 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. Sometimes the program itself has options to repair the most popular RNC file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted RNC files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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. It is best to move RNC to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file RNC to close. However, some background programs may block the RNC file while scanning. If this does not work either, restart the device.
