The access properties = of files and folders make sense only when you access them through the = specific OS. So NTFS can be read by other Oses, the same as ext2fs and other file systems of GNU/Linux. When I couldn't login to Win2K in the past because some application messed up the OS I did not lose my files. I = reinstallled Win2k without reformating the drive, I was getting my files to a CD and = then made a clean install (with formatting of the HDD). The same things apply to all OSes including GNU/Linux. If you want to = secure your files against theft you have to encrypt them, either using a third-party program or facilities of the OS. NTFS in Windows 2000 and later provides the ability for encryption using = a key randomly produced for each account. Programs that reset the password from the outside by deleting or editing some file (I do not know the OS internals) have also aas a result that key to be erased so files = encrypted via EFS (the encryption part of NTFS) from that user account become unaccessible.
