The WR! file extension is associated with the discontinued Lotus 1-2-3 spreadsheet application. Lotus 1-2-3 was originally available for MS-DOS and was later released for Microsoft Windows.
A .wr! file stores a compressed Lotus 1-2-3 spreadsheet, including the worksheet data and other spreadsheet content used by the program.
The format is obsolete and is no longer in common use. Files of this type may require the original Windows version of Lotus 1-2-3 or a compatible older environment.
Use the Windows version of Lotus 1-2-3 to open and work with a .wr! spreadsheet file. Current operating systems may not run this discontinued software directly, so an older Windows environment may be required.
If Lotus 1-2-3 cannot open the file, it may be necessary to use the original environment in which the file was created.
Open the .wr! file in Lotus 1-2-3 and save or export it to a spreadsheet format supported by the installed version. The available export formats depend on the version of Lotus 1-2-3.
The original Lotus 1-2-3 software is usually needed for conversion.
