Jigsaw variant ransomware-affected file
File type: Ransomware encrypted file
Files with the lcked file extension are files encrypted by a variant of Jigsaw ransomware. The extension identifies an affected file rather than a normal file format.
Encryption prevents the original content from being opened normally.

Jigsaw ransomware encrypts users' files and demands payment in bitcoin for recovery. The lcked file extension is associated with one of its variants.
This variant uses a different background picture. An lcked file contains the encrypted contents of an affected original file and is not a separate document format. Recovery requires a decryptor that supports this variant; the extension itself does not restore the data.
An lcked file cannot normally be opened by its original application. It must first be decrypted with a Jigsaw decryptor that supports the particular variant, if such a decryptor is available.
After decryption, the restored file can be opened with software that supports its original format.
There is no meaningful conversion from an encrypted lcked file. Decrypt the file first; the recovered file can then be converted or exported using software that supports its original format.
