In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

+<h1>Journaling File Systems</h1>
+<p>When a file-hosted VeraCrypt container is stored in a journaling file system (such as NTFS or Ext3), a copy of the VeraCrypt container (or of its fragment) may remain in the free space on the host volume. This may have various security implications. For
+ example, if you change the volume password/keyfile(s) and an adversary finds the old copy or fragment (the old header) of the VeraCrypt volume, he might use it to mount the volume using an old compromised password (and/or using compromised keyfiles using an
+ old compromised password (and/or using compromised keyfiles that were necessary to mount the volume before the volume header was re- encrypted). Some journaling file systems also internally record file access times and other potentially sensitive information.
+ If you need plausible deniability (see section <a href="Plausible%20Deniability.html">
+<em>Plausible Deniability</em></a>), you must not store file-hosted VeraCrypt containers in journaling file systems. To prevent possible security issues related to journaling file systems, do one the following:</p>
+<ul>
+<li>Use a partition/device-hosted VeraCrypt volume instead of file-hosted. </li><li>Store the container in a non-journaling file system (for example, FAT32). </li></ul>
