Folder Lock allows to protect the certain files and folders, hiding them, and thus does inaccessible to another's eyes. The size of a file or a folder thus can be any - though, for example, 50 Gb. For reception of access to the latent data it is enough to start Folder Lock and to enter the correct password. Management of the program very simple - is supported a method drag drop (has dragged-> has lowered-> has hidden).
