Folder Lock is Microsoft Windows software used to protect personal data with 256-bit encryption. An .flkw file is an encoded container that contains encrypted and protected data.
The file belongs to Folder Lock's encrypted-data workflow and must be handled by Folder Lock. It is not a general-purpose exchange format, so its contents are normally accessed by decrypting them in the application.
Use Folder Lock on Microsoft Windows to open or decrypt an .flkw file. The file may not open correctly in other applications because its contents are encrypted.
An .flkw file cannot normally be converted directly to another file format. Decrypt it with Folder Lock and export or save the recovered contents in their original formats, where available.
