Locker Mac

Locker is a little application to lock and unlock files and folders.

With Locker, you can:
lock file/folder in the same way Finder Get Info does [not very useful]
batch lock/unlock : drag a folder full of files/subfolders, some locked and Locker will unlock everyhing with one click.

A locked file can be opened but cannot be modified.

A locked folder can be opened (see its content in finder) but cannot be modified (add or remove files or modify files).
