How to open RFN file?

The most common problem when using RoboForm Safenote Format is that a specific RFN is not associated with the program. This is manifested by the fact that RFN 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 RFN 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 RoboForm for Chrome

The first step is to check if the computer has the RoboForm for Chrome program installed. This can be achieved by typing RoboForm for Chrome into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support RFN files.

Programs to open RFN file

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

Step 2. Create association of RoboForm for Chrome with RFN files

If, despite the installed application, the RFN file does not start in the RoboForm for Chrome 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 select the desired program. 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 RFN file with the RoboForm for Chrome application.

Step 3. Update RoboForm for Chrome to the latest version

If, despite the association of the RoboForm for Chrome program with the RoboForm Safenote Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Siber Systems, Inc. website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the RFN file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our RFN file. However, remember that not every infected RFN file can be recovered, so it is important to take care of regular backups.
Older version of RFN 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged RFN files. The easiest way to restore the file is from a backup or by contacting Siber Systems, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted RFN 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. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move RFN to a different directory.
This problem only occurs with more complex files. In this case, the RFN file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file RFN to close. Some anti-virus or backup software may occupy the RFN file for a certain period of time. If nothing helps, please reset the device.
