The 069 file extension is associated with several archivers or compression tools, which are using, or did use in the past, the 068 file extension for its multi-volume files or archives, such as Winrar or 7-Zip.
The general file sequence is 001, 002, 003, etc.. and you will need all parts of the multi-volume archive to successfully extract the content.
Use WinRAR compression utility to extract archive contents and start with first archive (first archive file has mostly file extension rar or 000 or 001).

Winfunktion Mathematik is an older German mathematics program released in 1998. In version 8.0, files with the .069 file extension stored data for Julia set mathematical fractals.
The file is part of the program's native data formats and is intended to be used with the fractal features of Winfunktion Mathematik. The current and latest version of Winfunktion Mathematik is 18, but it is not established whether version 18 continued to use .069 files for Julia set fractals.
Open the file with Winfunktion Mathematik Plus on Microsoft Windows. Use the program's file-open command and select the .069 file.
Because this is an older, program-specific format, current Windows software may not recognize it without a compatible installation of Winfunktion Mathematik.
Open the file in a compatible version of Winfunktion Mathematik and use any export options provided by that program.
