The file extension SILK identifies a file that exists in the symbolic link format. This file format was developed by Microsoft to transfer data between spreadsheets and other database applications.
The files contain text that uses semicolons to separate the contents of a cell by column, line, format, and content. These data are stored in ANSI format.
Complex formulas are stored in SYLK codes.
By default, the ending slk is used for these files. Occasionally, the syk ending occurs.
Although Microsoft did not release the specifications of SYLK, several variants of the format are supported by a number of applications. For a trouble-free support we recommend changing the file extension to slk.
