Files and FoldersNotes

Attributes

By selecting multiple files or folders in My Computer or Windows Explorer, you can perform many of the previously mentioned tasks simultaneously on the selected files or folders. When multiple files are selected and their collective properties viewed , a checked attribute checkbox with a gray interior indicates that some of the selected files have the attribute set and others have it cleared.

If you set the Hidden attribute for a file on the desktop and My Computer is configured to hide hidden files from view, the file will remain visible but ghosted until you log off and then log on again, at which time it will be hidden from view.

There is another type of attribute called System on both FAT/FAT32 and NTFS volumes . The System attribute is not accessible from the GUI and can be accessed only from the command line using the attrib command. Critical operating-system files have their Read-only, Hidden, and System attributes all set by default.

If the Hidden attribute for a file has a checked attribute checkbox with a gray interior, it means the file has both its Hidden and System attributes set.

The term attribute has a different meaning in the context of Active Directory.

Compression

You can't both compress and encrypt a file at the same time.

You must have NTFS write permission on a file or folder in order to compress it. In order to compress a file, you need enough free space on the disk to hold the file in both its compressed and uncompressed states.

Encryption

You can't encrypt a file that is marked Read-only or System.

If you copy or move an encrypted file within or between NTFS volumes, it remains encrypted. If you copy or move it to a FAT/FAT32 volume or a floppy disk, it is decrypted.

Encrypt only datafiles; encrypting program files adds unnecessary system overhead.

When encrypted files are copied between computers over the network, the data is sent in an unencrypted state. To encrypt data sent over a network, you must use SSL or IPSec.

Remember, to read an encrypted file, you don't have to decrypt it manuallyWS2003 does that automatically for you. You need to decrypt a file only when you want to share its contents with other users.

Folders are actually not encrypted themselves , just marked as such. The marker tells the operating system that any files that are later added to the folder should be encrypted, if they aren't already.

Encrypted files can't be accessed by Macintosh clients .

Backups of encrypted files are also encrypted, provided they are on NTFS volumes.

If you have partitions in a WS2003 system that are formatted using NTFS for NT 4.0 or earlier and you attempt to encrypt files on this volume, a chkdsk operation is run and the filesystem is converted to the WS2003 version of NTFS.

Users with roaming user profiles can use the same encryption key with trusted remote systems.
