The contents and purpose of an .rl_ file cannot be identified reliably from the extension alone. There is no confirmed vendor, application, platform, or format specification associated with this record.
Because its format is unknown, the file may belong to a specific application or may be an incorrectly renamed file.
No dedicated program is known to open an .rl_ file. The file should be handled with the application that created it, if that application can be identified from the file's source or surrounding files.
An .rl_ file cannot be reliably converted without identifying its actual format and creating application. No specific conversion or export method is known for this file extension.
