Besides all the above, there are encrypted files that contain a hidden message that can also be cracked by professionals.
The file names are also analyzed as this can determine a whole host of questions like when and where it was created, thus helping them in figuring out the connection between the storage files and online data transfer. Files are usually connected to an exact server and computer from which they were uploaded. This will give investigators ideas as to where the system is situated. You could match filenames to any listing on the person of interest’s hard drive as a way of validating any form of digital evidence they may have collected over the course of research.
There are also other tools that can help in the retrieving of data such as deleted files.
