File Compression and Encryption
Today we are discuss more effective informative idea of File compression and ﬁle encryption are two special features of the NTFS ﬁle system that are implemented as advanced attributes.
1) File compression is a way to save disk space by removing blank or repeated characters within ﬁles. Windows ﬁle compression is rarely used, partly because disk space on most systems today is relatively plentiful, and partly because there are other ways to reduce ﬁle size, such as with a ﬁle-compression utility like WinZip®, that creates a new, compressed ﬁle that you can copy to other media or email to other users.
2) File encryption is an NTFS security measure that scrambles the contents of a ﬁle so that only the person who encrypted the ﬁle can open it, even if the disk containing the ﬁle is physically removed from the computer and loaded into a different computer system. File encryption is a good way to protect data on portable devices such as laptop computers.
