The CJ file extension can reference several types of files, each with its own application uses and methods for opening. It's crucial to understand the context within which a CJ file is utilized to determine the best course of action. The following sections will discuss the various formats and ways to use files with CJ extensions.
CryptLoad files
In application scenarios associated with software such as CryptLoad, the CJ file extension is useful. CryptLoad is a popular automated downloader, which primarily handles one-click-host downloads. The CJ files in this case are actually package lists, used to load and download a group of links. Such files can be used by opening CryptLoad and selecting the package list to execute.
You can download the latest version of CryptLoad from their official website (https://www.cryptload.info/).
Jigsaw Ransomware Encrypted Files
Less benignly, the CJ file extension might refer to files encrypted by the Jigsaw ransomware. Jigsaw is a form of malicious software that encrypts files on a victim's computer and then demands payment to decrypt them. If a CJ file is an encrypted file, you are likely dealing with a serious security threat and immediate action is needed.
Online guides and resources on how to handle such threats are available on websites like Emsisoft (https://www.emsisoft.com/ransomware-decryption-tools/jigsaw).
