Dependency has nothing to do with where the files are located. Most programs in Linux share libraries, and place the libraries under a separate directory for organizational purposes. Sure, you could place a copy of the library under each program's directory, but this wastes space and defeats the purpose of shared libraries in the first place. ALL operating systems that use shared libraries, including Windows and Mac OS X, require dependency tracking for proper operation. The only way this could be eliminated is if we all went back to static binaries instead.

To lock folders and files in Windows XP, 7 or other systems, there are built-in features. You can lock your folders and files with your Windows login password by this method. Since it is locked with your system password, it is not portable and is not as secure as you might expect. I think that's why you ask for some software here. A third-party folder lock software will be very helpful. I usually use Advanced Folder Encryption since it can lock folders in both my hard drive and USB drives.
Unfortunately, making folders on an iPhone requires iOS 4 or higher. The original iPhone only supports up to iOS 3 software.
Use the computer file management system. You can organize files in directories, folders, and sub-folders.
