There is only one file type that uses the .OPTS extension:
Linux Configuration Options File
Options file used for installing and configuring various Linux applications and hardware devices; contains plain text instructions for an installer or program; can be used for overriding setup and installation options, or for specifying required application parameters.
Users sometimes create OPTS files when setting up network cards or other PCMCIA cards in Linux. One OPTS file can be found on the Knoppix or DSL Linux boot disks for setting boot options.
