Monitor, Manage, and Troubleshoot Access to Files and Folders

Windows XP Professional administrators must understand the details behind NTFS

compression precisely because it is so easy to use. As the feature increases in popular-

ity, so will the number of users experiencing problems. Although any user can com-

press a folder using Windows Explorer, only the system administrators can explain

exactly how compressed folders affect system performance and available disk space.

Although Windows Explorer provides the most user-friendly interface into the details

of compression, the Compact.exe utility is useful to administrators who need to com-

press multiple folders on a system or compress folders on many different systems.

NTFS file compression does not obey the same rules of inheritance as other aspects of

Windows XP. For example, files that are copied always inherit the compression state of

the destination folder. However, if you move files within a single volume, the compres-

sion state of the file is retained. To make things more confusing, files moved between

different volumes inherit the compression state of the destination folder.

Windows XP Professional includes the ability to restrict users’ access to files and folders

using NTFS file permissions. For example, a user that has Full Control permission to a

file might alter other users’ rights to that file by modifying the discretionary access con-

trol list (DACL). Similar to the way Compact.exe provides a command-line alternative

to enable compressing within Windows Explorer, Cacls.exe provides a command-line

method for modifying file permissions.
