True, this is always an option, but could there be a more elegant way? I started exploring and then came across a curious, niche tool called extcv , specifically designed to extend, or rather, resize existing TrueCrypt volumes without reformatting. Let us explore. Ah yes. This product was discontinued not that long ago in a rather dramatic fashion by its owners, with some big claims how it was not secure and such. If you put all the fuss and fear aside, TrueCrypt is still a decent encryption product that can help you keep files secure, especially on mobile devices like notebooks and external disks.
There are other programs of this kind - including direct successors to TrueCrypt, but that's not the point. We're here to discuss the size and resize issue with volumes, and how to do this elegantly without too much work or overhead. Anything else is just needless security paranoia and philosophy, and that's not why we're here.
If you're using TrueCrypt, you're using it, and you probably can't or won't just throw it away. The second piece of this foreword is to warn you - changing filesystems and containers, encrypted or not, is always a risky operation that can end up with a total, irreversible loss of data. I strongly advise against resizing TrueCrypt volumes unless you have a second backup, preferably unencrypted, of the data stored inside, even for a very short duration while you carry out the resizing work.
All that said, let's move on. There are several checkboxes you must tick. For extra security, the portions of the randomness pool, master key, and header key can be prevented from being displayed by unchecking the checkbox in the upper right corner of the corresponding field:.

However, several items deserve further explanation: Hash Algorithm Allows you to select which hash algorithm TrueCrypt will use.
Encryption Algorithm This allows you to select the encryption algorithm with which your new volume will be encrypted. Quick Format If unchecked, each sector of the new volume will be formatted. Quick format is much faster but may be less secure because until the whole volume has been filled with files, it may be possible to tell how much data it contains if the space was not filled with random data beforehand.
Dynamic Dynamic TrueCrypt container is a pre-allocated NTFS sparse file whose physical size actual disk space used grows as new data is added to it. Cluster Size Cluster is an allocation unit.

KookyMan , Mar 29, Therefore, TrueCrypt container cannot be recogized by file signature analysis. Even though we can not use file signature analysis, there are a few indications we can use to check whether a certain file is an encrypted TrueCrypt container file:.
Also check if you can find a history.
