To support data recovery on all existing file systems and undelete all imaginable file types Disk Drill features 3 scanning and recovery methods:
Deep Scan
To really get deep
Regardless of what happened to your disk and which file system was there before, Deep Scan attempts to extract every bit of data still remaining in any binary mess: formatted drive, lost partition, etc. It's slow and based on file signatures it already knows. The list of known file types is constantly updated. Deep Scan is your last call for help if nothing else works or if data loss is really severe. While it's not capable of recovering original file names and locations, as well as other meta-data of recovered items, Deep Scan does an impressive job of getting files that were deleted/lost many days ago.
Undelete
from Recovery Vault
Recover any file or folder exactly as it was before deletion on disks and partitions protected with Recovery Vault. All file types supported, all original properties are recovered, this method is extremely precise
Quick Scan
HFS+, FAT & NTFS only
Scans existing journal or file table for deleted items. Requires a working disk or partition. Is very fast, but not precise as not all deleted files still exist in the areas of search
Recover lost documents, photos, images & more!
Deep-scanning retrieves all major file types analyzing all your binary space in search for known file signatures and bytes sequences. Deep Scan is capable of recovering any of the following files:AI (Illustrator images), CR2 (Canon raw images), DNG (digital negative images), JPG/JPEG, TIFF, BMP, GIF, MAX (3DS Max scene), NEF (Nikon raw format), PNG, PSD (Photoshop images), RW2, VSD (Visio drawing), SKP (SketchUp Document), AVI, DV (digital video), M2TS (Blu-ray video), VOB, ORF (Olympus raw images), FFF (Hasselblad raw images), IPA (iOS applications), MMAP (MindManager maps), RVT (Revit), FP7 (FileMaker document), ENL (EndNote Library file), APK (Android applications), C4D (Cinema 4D), RM (Real Media files, also known as RV, RMVB), RA (Real Audio format), FLAC (lossless audio), MA, MB, MP (Maya related files), ITL (iTunes library file format), DB3 (SQLite3 database, same as DB file in iPhoto library and many other mac software), .h and .m (Xcode 3/4), AEP (Adobe After Effects CS5) ...show all

While Disk Drill is a great data recovery software for novice users, there's a number of features Mac professionals will find extremely useful:
Advanced scanning sessions management
Save and Load scanning sessions to switch between multiple media during data recovery. This is also invaluable for Deep Scan, which may take hours - scanning progress is saved hourly. You can be sure the progress is safe and not lost. Pause, save a session and get back to your scanning process later, when you have more spare time.
Various flexible filtering, searching and sorting options help you locate exactly the items you need recovered among hundreds or thousands of files usually available after deep-scanning. Convenient preview lets you check the contents of the files you are about to recover: images, video, music, documents, etc. By using Mac OS QuickLook approach, Disk Drill's preview feature is capable of showing even formats specific to a certain Mac.
