I setup file restore on a Windows 8 computer.

Backed up all the files to a NAS.

Wiped and reloaded 8.1 pro and did a file restore.
All of my files, except one large file, restored.

The file that didn't was a 1 gig TrueCrypt (VeraCrypt) file in the root of "documents".

When I browse out to my NAS, I see 5 files.
One of them is named: TCvol (2014_12_09 02_17_05 UTC) and it is 200 megs.
I believe these 5 files need to combine themselves again to restore my original 1 gig file, but I cannot find any documentation.

Pretty much everything shows that you open file history restore and your data should appear there.

Hi,

It should be caused that Windows Server Backup cannot recognize the encrypted file - I cannot confirm how the third party application (TrueCrypt) work, it seems that it will split an encrypted file into several files and Windows Server Backup only restored files physically. You can contact TrueCrypt support about this issue. 

I searched on your website and found several threads which related to get TrueCrypt working with Windows Server Backup. Specifically to your current issue you can confirm with them about any suggestion to get file recovered or how to do such backup job for a healthy recovery.
