The frf file extension is associated with ABBYY FineReader, an OCR and PDF application developed by ABBYY for Microsoft Windows.
An FRF file stores internal page data used while FineReader processes documents. It belongs to FineReader's internal working data and is not normally intended for exchange between applications.
Because the file is application-specific and may depend on the FineReader version that created it, it should generally be kept with the related FineReader data. It is not a standard user document format.
An frf file is not normally opened as a standalone document. It is intended to be used internally by ABBYY FineReader on Microsoft Windows.
Use FineReader to open the original document or related FineReader data instead of trying to edit the FRF file directly.
There is no usual standalone conversion method for an FRF file. It contains internal FineReader page data, not a document intended for conversion.
To create a usable output file, open the related document in ABBYY FineReader and use its export or save options to produce a supported document or PDF format.

The FRF file extension identifies first-reduction data from Ginga, Japan's X-ray astronomy satellite. FRF files contain data transported from the satellite for use in the mission's data-processing workflow.
Open a .frf file with Ginga mission data-analysis software or another astronomy application that specifically supports Ginga first-reduction data.
If the file came from an archive, consult the archive's documentation for the required analysis tools.
Conversion normally requires Ginga-specific astronomy software or a mission-data processing tool. Consult the documentation for the software or archive that supplied the file.
