What is an FLKB file?
Encrypted archive, or "locker," created by Folder Lock, an application used for protecting sensitive files; contains a collection of files that can only be opened using the locker password; uses NTFS file system formatting and supports unlimited file sizes; used for backing up personal documents and other sensitive files.
FLKB files are referred to as Basic Lockers. Folder Lock also supports Portable Lockers (.FLKA extension), which have a 4GB file size limit. While Portable Lockers can be backed up using NewSoftware's online backup service, Basic Lockers cannot.
NOTE: FLKB and FLKA files were introduced with version 7 of Folder Locker. Previous software versions use .FLK files for lockers.
