What is a JLK file?

JLK files mostly belong to JLK Editor. The JLK file format can refer to two distinct types. The primary use is as a Java Keystore File, which holds cryptographic keys and digital certificates for Java applications. It is managed with specialized tools such as those provided by the JLK Editor.
In other cases, the file works as a Kingsoft Spreadsheets data file where it stores spreadsheet data, including cell values and formulas, and must be opened by Kingsoft Spreadsheets software.

If the file is a keystore, it contains secure key data used for encryption and authentication.
If it is a spreadsheet data file, it holds structured table information.
Using the wrong application to open the file may cause viewing errors or even data loss.
Always back up your file before making any edits.

FilExt.com tip: Few users know that the same JLK extension can indicate two very different types of files. Verify which use applies before altering the file.
