In the advanced section of the file properties there is an option to encrypt files. So can still open them on a synced machine using Live Mesh?

I looked over the blog post and it is very nicely detailed over the Mesh security which I see is relatively good. I have decided to use a password protected zip file so that I can open the file on my netbook rather than use the NTFS file system security to be sure I can read it. I am disappointed that Mesh only uses AES-128 when AES-256 is so much stronger.

NTFS compresses files using a variant of the LZ77 algorithm. [21] With 4KB clusters, files are compressed in 64KB chunks.

Is there any way to backup the keys for the encryption so that if the system is crashed the files can be opened with the keyring again My MVP is for the Windows Desktop Experience, i.e. Windows XP, Vista and Windows 7 IT Remote Assistance is available for a fee.

Vegan, You mean the keys for EFS(Encrypted File System) and yes it is possible. This technet article describes how: http://technet.microsoft.com/en-us/library/cc756891(WS.10).aspx And this is also a good link. http://www.nirmaltv.com/2010/07/08/how-to-backup-encrypting-file-system-efs-certificates-in-windows-7/ Kind Regards DFTIM me - TWiTTer: @DFTER

I am thinking its an idea to encourage world+dog to backup the keys so that when the day comes when the system craps out they they do not lose data galore.
