The Sleuth Kit, a collection of free and open-source software for digital forensics, can be used to do in-depth studies across different file systems.
When you launch Autopsy, you'll have the option to either begin a new investigation or open a previously saved file. If you want to start investigating a new case, you'll need to load a forensic image or a local disk. When the analysis is done, you can choose which results to look at by clicking on the nodes in the left pane.
There are a bunch of decent tools out there that offer the same array of services as The Sleuth Kit. And it can sure get confusing to choose the best from the lot. Luckily, we've got you covered with our curated lists of alternative tools to suit your unique work needs, complete with features and pricing.
