The IBM 4690 Operating System, also known as 4690 OS, is a point-of-sale operating system developed by IBM and now owned by Toshiba.
An rsq file contains data used by IBM 4690 Operating System. Its exact contents depend on the system component that created it, and it is not intended as a user-editable document.
4690 OS is a legacy operating system for retail point-of-sale equipment and related store systems. Files of this type are normally encountered only on installations that still use the IBM or Toshiba 4690 software environment.
Open an rsq file only with the IBM 4690 Operating System or compatible Toshiba 4690 retail software that created it. The file is normally processed by the relevant point-of-sale system rather than opened manually.
Do not edit or rename the file before checking with the administrator of the 4690 OS installation, because it may be required by the system.
There is no known general-purpose converter for the rsq file format. It is a system data file rather than a document intended for export.
If the associated 4690 OS application provides an export or migration function, use that function instead of converting the file directly. Otherwise, retain the original file and process it within the compatible retail system.

Record marked as obsolete and not updated for a long time.
The rsq file extension is associated with SpeedQuest, a software package from Speedwell for designing and creating questionnaires.
An rsq file contains data used by SpeedQuest. The format is obsolete and may be encountered mainly with older SpeedQuest projects.
Open an rsq file with the original SpeedQuest software from Speedwell. Because the format is obsolete, the software may no longer be available or may require an older system.
If SpeedQuest can open the rsq file, use any export functions provided by the software to save the questionnaire data in another format.
