Question: What is an WK! File?

Have you found, downloaded or received an WK! file, but don't know which software program is required to open it?

Before attempting to open an WK! file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.

Answer: Files which are given the .WK! extension are known as Lotus 1-2-3 Spreadsheet files, however other file types may also use this extension. If you are aware of any additional file formats that use the WK! extension, please let us know.

How to open a WK! file:

The best way to open an WK! data file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the WK! file.

This data file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format.

Please check back soon for more information as we are constantly updating our file descriptions based on search frequency.

Tip: Try to open the WK! file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.

The WK! file extension is a Lotus 1-2-3 file that was compressed and saved using a program called SQZ!. Not sure where you can find the program at this point.

I have a copy of SQZ! version 1.5 on both a 3.5 floppy disk and on my hard drive. It is a DOS program, and I am not sure how to run it to uncompress the spreadsheet files. Incidentally, SQZ! compressed *.WKS files as *.WK$ and *.WK1 files as *.WK!. Any help with how to run this file in the DOS box under either Windows XP or Windows 7 would be appreciated.
