File Properties: Advanced Attributes: Encrypt

Can someone explain how the 'Encrypt' tickbox in the advanced file attributes works.

I thought it encrypted the file so that it can only be viewd by the user who encrypted it. But when I co0py the file accross the network to a server with a different login, I can open the file and it is still plain text.

This is how EFS works ( I assume your doing the following http://www.microsoft.com/windowsxp/using/security/learnmore/encryptdata.mspx http://support.microsoft.com/default.aspx?scid=kb;en-us;307877&sd=tech  )
EFS will only keep files encrypted if they are on NTFS drives, so if you encrypted the file/folder on ntfs, and copied it to a FAT or other format that is not NTFS, the encryption is lost.
Administrators and or owners of files can read EFS encrypted files
