Windows 7: Can I encrypt my user directory transparently?

Can I encrypt my user directory transparently?

hi all, i need to secure my user directory transparently, here is my scenario:

using windows_7 64-bit;

i have very important development files on this pc, i want to secure these files under my user directory so that they cannot be read in case of physical access / stolen hardware.

this hardware does not have tpm so i cannot use bitlocker, not that i would anyway since the only thing it gives is a false sense of security.

an option is to create a truecrypt container, however this will be limited to a fixed size, and the nature of development i cannot safely guess the size of the container for the next year or two. i also cant do full partition encryption cos i cant reinstall this work pc. lets just say the company does not give a shit about securing the dev files :/

going into the folder properties > general tab > advances attributes we can check the "encrypt contents to secure data" option, i can't find any details on what encryption is used or how secure it is. on top of that, file descriptors are _not_ encrypted, only contents. so booting with a live cd you can still see the file structure of individual files. much more exposed than im comfortable with.

i want this to be transparent, ie i log in with my domain account and my user data is decrypted, i log out and the data is secured again. i don't want to mess around with a) mounting separate encrypted volumes or b) enter multiple passwords to log in and decrypt, and also c) not expose the file structure, but rather a blob of encrypted data, less vectors of attack if you know what i mean.

so, the question is... what can i do to secure my user directory, transparently?

I am going to suggest TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows 7/Vista/XP, Mac OS X and Linux This program is great you can make a seemingly usual file maybe a .iso file (maybe what I use, cause iso's can get quite large). and have everything encrypt to inside that file

As I said above I can't reliably predict the size of the container for the next 2 years, but I guess it's just one of those things. i won't be securing this data after all, their lack of insight isn't my problem any longer

With truecrypt you can set it for an UNGODLY size 500 GB to 500PetaBytes and have it grow dynamically9It doesn't allocate all at once)
