Modern network-ready and secure operating systems provide us with a very useful concept of Resource Access Control. It generally means the ability to grant different access permissions to individual resources (files and folders) for different users of the system, local and network ones. For example, a certain file can be permitted to be read but not written to; or certain folders can be opened and programs in them executed, but files in them cannot be read or written (e.g., for guest users).
Unfortunately, Microsoft doesnt provide tools for controlling access with Windows XP Home version (although this capability does exist within the system and is provided with the superior versions). Nevertheless, if you are Windows XP Home user, you can use cool File Security Manager software to obtain the control over all permissions.
File Security Manager integrates itself into Windows Explorer and lets you set permissions for files and folders quickly and easily. You can either follow the simpler way to doing this by using the wizard (which provides useful presets), or utilize the more advanced possibilities given with property sheets dialog.
Besides permissions, you can also modify the «ownership» of a folder or file (set yourself as owner). File Security Manager also provides the useful feature of «secure file deletion», which means the file you delete cannot be restored.
