In the fast-paced world of digital forensics, time is often the most critical factor. Investigators frequently need to make rapid decisions on-site without the luxury of waiting hours for a full data acquisition. This is where ADF Solutions’ Preview Mode becomes an indispensable asset in your toolkit.
What is Preview Mode?
Preview Mode is a powerful feature designed to streamline the initial stages of a mobile device investigation. It allows you to quickly review files and artifacts on a device in real-time, bypassing the need for a full logical data acquisition upfront. By establishing a connection, the viewer populates data as it is collected, providing immediate access to files, properties, and metadata. Preview mode utilized standard protocols and methodology ensuring you are complying with data integrity, authenticity, and reliability.
This eliminates the tedious process of manual thumb-scrolling and ensures that you can begin your analysis almost instantly.
Pro-Tip for iOS Investigations
When working with iOS devices, there is a specific configuration that can save you significant frustration. By default, iOS may attempt to convert multimedia files during transfer. This conversion process can lead to failed transfers and, in some cases, corrupt the connection between the device and your workstation.
To ensure a stable connection:
Navigate to Settings → Apps → Photos. Under the “Transfer to Mac or PC” section, change the setting from Automatic to Keep Originals. This simple adjustment ensures that files are transferred in their native format, maintaining connection integrity.
Getting Started: A Step-by-Step Guide
Setting up a Preview session is straightforward. Follow these steps to begin your real-time review:
- Initialize: Navigate to Investigate Device → Preview.
- Connect: Click the “Add Phone” button. If the device isn’t immediately detected, the built-in connection wizard will guide you through the necessary steps.
- Configure: Select your destination folder for saving data and assign a unique Preview Name. If your workflow requires specific documentation, use the “Forms” button in the right-hand toolbar.
- Proceed: Ensure you have a valid license present (Computer license, ADF Authentication Key, or licensed Collection Key) and click PROCEED.
Navigating the Real-Time Viewer
One of the strongest advantages of Preview Mode is its dynamic nature. After a few seconds of initial caching, the viewer opens, and you can immediately browse Pictures, Videos, or Files. You do not need to wait for the entire collection process to conclude; if you switch views—for instance, moving from Pictures to Videos—the system intelligently reprioritizes the collection sequence to fetch the data you are currently looking at first. If you observe what you need to make a decision the preview can be stopped and everything collected up to that point is saved and ready for further analysis and reporting.
Use Preview Mode when: You need immediate answers, want to verify the presence of specific evidence on-scene, or need to decide if a device warrants a full forensic examination.
Proceed to Full Logical Acquisition when: Your investigation requires a more comprehensive data set, deep parsing of third-party apps, or a complete profile analysis for courtroom presentation.
By integrating Preview Mode into your workflow, you can significantly reduce the time spent on devices that may not be relevant to your case, allowing you to focus your expertise where it matters most.
Conclusion
Preview Mode helps digital forensics professionals make faster, more informed decisions by providing immediate access to relevant files and artifacts—without waiting for a full acquisition. Put it to work on your next investigation to quickly identify potential evidence, reduce unnecessary device examinations, and accelerate the path from collection to action.
