&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{wikify}}&lt;br /&gt;
{{expand}}&lt;br /&gt;
&lt;br /&gt;
The [[EnCase]] suite of tools can generate 'hash maps', or 'EnMap' files, which allow users to identify chunks of files when the whole file is not available. This data is stored in a file with a .EnMap extension and contains piecewise [[MD5]] hashes of the file. Each EnMap file has the following format:&lt;br /&gt;
&lt;br /&gt;
The file has an ASCII header, ENMAP V4, or in hex 45 4e 4d 41 50 20 56 34 0b 00 00 00.&lt;br /&gt;
&lt;br /&gt;
This is followed by a Unicode representation of the original filename.&lt;br /&gt;
&lt;br /&gt;
There is then an [[MD5]] hash of the entire file. This hash is followed by three bytes of zeros, and then a hexadecimal representation of each piecewise hash.&lt;br /&gt;
