What is an RFO file?

RFO files mostly belong to RoboForm. An RFO file is a secure data file used primarily to store encrypted password information for RoboForm.
It functions as a RoboForm password data file, meaning it contains sensitive login details that only the RoboForm application can read after decrypting them.
In some instances, an RFO file can also be an encrypted license file used by RFO Analyzer to verify software licensing.

• RoboForm usage: Open these files with RoboForm to access and manage your encrypted passwords. Visit RoboForm for details.
• License usage: If the file is a license file, it must be used with the corresponding RFO Analyzer software.

FilExt.com tip: Ensure you do not alter these files manually and always keep backups to maintain your security and data integrity.

RFO file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening.
