Data Doctor Recovery Memory Card vs DiskDigger

Data Doctor Recovery Memory Card has no write-up on Specifiction yet; its figures are above.

DiskDigger recovers deleted files from computer-readable media, including hard drives, USB drives, memory cards, optical discs and floppy disks. It combines filesystem-based recovery with free-space scanning, and supports file systems including FAT, FAT32, NTFS, exFAT, ReFS, ext4 and HFS+. Recoverable items can be viewed in lists or thumbnails; previews are available for images, documents, some audio files and ZIP archives. Advanced scanning covers E01/EWF, VMDK, VHD/VHDX, VDI, QCOW2 and raw binary disk images.

The product is available for Windows, Linux, macOS and Android. Windows users can scan and preview without paying, but must purchase a personal license to save recovered files; commercial use requires a commercial license. Linux use is free, while Linux and macOS builds are described as experimental beta versions. Android's free version recovers photos and videos, with video recovery requiring root; other file types and FTP uploads are available in Pro, and non-photo recovery requires root. DiskDigger says it sends no analytics or telemetry. Recovery may fail if deleted contents have been overwritten or files are fragmented.
