Frequently Asked Questions
Professional file forensics and security auditing on macOS.
What is File Deep Info?
+
File Deep Info is a professional-grade file forensics and deep inspection tool for macOS. It allows you to go beyond surface-level information to uncover hidden data, verify true file formats, extract embedded objects, and audit metadata with surgical precision.
How does the True Format Identification work?
+
We use a triple-engine detection system: MIME/Magic Number analysis, macOS native UTI framework, and 97 deep signature scanners. This identifies a file's real identity even if the extension has been changed or removed (e.g., an executable disguised as a PDF).
What kind of "hidden data" can it find?
+
It depends on the format, but for Office files, it finds hidden rows/sheets, white text, and revision history. For PDFs, it reveals hidden layers and JavaScript. For images, it identifies EXIF GPS coordinates and LSB steganography.
Does File Deep Info collect or upload my files?
+
No. Security and privacy are our top priorities. File Deep Info is a 100% offline, local-only application. It does not have any network functionality. Your files and analysis results never leave your device.
What is the difference between Free and Pro?
+
The Free version includes full fingerprint analysis, format detection, and metadata extraction. The Pro version unlocks Shadow Data deep parsing, recursive multi-level analysis (Analyze in New Window), and unlimited embedded object extraction.
What are the system requirements?
+
File Deep Info requires macOS 11.0 (Big Sur) or later. It is fully optimized for both Intel and Apple Silicon (M1/M2/M3) Macs.
