Scan for and recover deleted files from memory cards and internal storage on rooted* devices.
The app uses rewarded video ads - restoration of any discovered file or data is completely free of charge. You can still buy the unlocker to remove all ads and enable background scanning.
Without a jailbreak/root access, Undeleter can only scan app caches for images.
*ROOT/SUPERUSER PERMISSIONS require that you modify the operating system on your device, visit this website for more information: http://www.androidcentral.com/root
App caches can contain images that would not otherwise be discoverable: you may find photos that were shared with you on social media but you never opened, or lower quality copies of images you have now or have deleted in the past. They may also contain images that have been preloaded by your browser or other apps on your device - even images of people you don't know. They can be filtered out using "Hide extant files".
File types: Journal scanning can discover files with any conceivable extension. Essentially these files are still on your volume with their data in allocated sectors. Journal scan is only available on EXT4 and derived file systems.
Deep scan heuristically scans for and recovers the following types of files: BMP, JPEG/JPG, PNG, MNG, JNG, GIF, MP4, AVI, MKV, MP3, OGG, OGM, WAV, FLAC, AMR, MP4A, PDF, SXD, SXI, SXC, SXW, ODT, ODG, ODS, ODP, DOCX, XLSX, PPTX, ZIP, JAR, APK, EPUB.
Data scanning is available for a select number of apps, including the system phone and SMS applications. Data will be recovered in the form or HTML files for WhatsApp and Viber, as we cannot merge third-party catalogs.
Shred/secure delete: Files found on free disk areas can be erased permanently in bulk using the Shred function. You can also use the system-wide Share menu to securely erase files directly through any other app, for example by opening the gallery, selecting a number of images, pressing the Share button and selecting Secure delete.
