I keep all my sensitive documents encrypted in Truecrypt volumes (don’t you?).  But I ran into a problem when I wanted to share a Truecrypt volume across my home network.  I had to setup the share every time I mounted the volume.

Then it hit me; my flaw was that I was trying to set up a share within the Truecrypt volume.  I needed to set up a share and then mount the TC volume inside that share.  But you can’t mount a Truecrypt volume to a directory.  Humm….

Enter Hardlink Shell Extension.  HSE will let you create Volume Mount Points in Windows.  That will let you “map complete local volumes onto arbitrary disk locations”.  So you can create a VMP (as a folder) and point it at the drive letter of your TC volume.  That way whenever you mount the TC volume to that drive letter, it will already be shared.

After installing the HSE, Mount your TC volume, right-click, and select “Pick Link Source”

pick-link

Now go to the drive you are going to set up your shared folder and right click.  Then select “Drop As…” and “Volume Mountpoint”.

drop-vmp

Now just share the resulting folder.

When you mount the TC volume (or any TC volume for that matter) to the drive letter you selected as your “Link Source” it will be shared.

    hi, do you have any idea on how to do the opposite, i.e. restricting access the mounted volume?

    here is my situation:

    i use a truecrypt volume to store my data on USB for access on multiple machines. when i mount the volume, it becomes visible to other people on the machine. i tried to set NTFS permission, but then i need to have the files accessible from multiple machines not belonging to the same domain. any suggestion?

    Lazy, I may need more info to try to answer your question. But if you are just trying to hide your mounted TC volume on and XP machine, the easiest way would probably be to use TweakUI. In TweakUI, you would go to My Computer and then Drives and uncheck the drive you want to hide.

    Or if you use the same drive letter to mount each time, you could then use a registry hack to hide it: http://tinyurl.com/33yzl8a

    This doesnt work for me… win 7 64, true crypt, when i try to share the resulting “mountpoint” folder win 7 tells me: “your folder cannot be shared”. Anyone know how to get past this?

    Daemonizer, if you try to create a mountpoint of another folder and share it, does it work?

    Turns out my sharing in windows 7 was completely messed up. I picked up an SSD (woot) and reinstalled windows 7, and now sharing works. However after creating the True Crypt volume and mounting it, selecting “Pick Link Source” on that new drive letter, and then going to the Drop As… menu, the only options I have are:
    Symbolic Link
    Junction
    Smart Copy
    Smart Mirror
    Delorean Copy
    Symbolic Link Clone

    I tried Junction and that seemed to work fine. Thanks for the suggestions and posting this page.

    I’m not using this for sharing, but to instead redirect a Zimbra Desktop message store to my encrypted volume. Works like a champ, thanks!!
