The format is obsolete and is not commonly supported by modern archive utilities.
File type category:

Date updated: October 24, 2026
Record marked as obsolete and not updated for a long time.
Player CDcheck used KEN files to store compressed data. The files belong to that program and are not a general-purpose archive format with broad software support.
Little technical documentation about the format or the original program is publicly available. As a result, modern software may not be able to identify or decompress these files.
The format is considered obsolete and may only be encountered in old Player CDcheck data.
Open a .ken file with Player CDcheck, if the original program is still available. Modern archive programs may not recognize this format.
If Player CDcheck cannot open the file, there is no reliably documented alternative opener for this obsolete format.
There is no established converter for the Player CDcheck compressed data format. If Player CDcheck can read the file, use it to access the data and then save or copy that data in a modern format.
Without the original program, direct conversion may not be possible.
