DiskTuna vs Puran Defrag

DiskTuna’s JPEG-Repair Toolkit combines JPEG-Repair for damaged photos with JpegDigger for recovering lost images. It runs on Windows 7, 8, 10, and 11 and processes files locally on the PC, without uploading them to remote servers. JPEG-Repair addresses corrupt headers, invalid markers, bad-sector damage, and JPEG bitstream errors with visual feedback. It can recover JPEG data from corrupt RAW photos such as Canon CR2 and Nikon NEF files, and does not re-encode JPEG images. The demo shows low-resolution previews; the full version enables high-quality saves. Repairing a corrupt JPEG header requires a reference photo made with the same camera and settings. The toolkit specializes in JPEG and specified RAW formats and does not repair PNG files. The listed plan includes both tools and is billed at €29.00–€49.00, excluding applicable taxes. Downloads are unsigned and may trigger Windows SmartScreen warnings, including after updates. The maker offers a refund only when the demo works on the files but the full version fails on those same files.

Puran Defrag is a free Windows utility for defragmenting files and optimizing hard disk drives. Its Puran Intelligent Optimizer moves frequently used files to faster disk areas, and directory consolidation can place directories in contiguous areas; that option works only on NTFS partitions. You can schedule defragmentation for startup, after intervals, or for chosen times on selected days. Boot Time Defragmentation handles system files such as the MFT, Registry, and Pagefile, or an entire drive. Low Priority Defrag uses resources when other processes are idle, so work can continue while defragmentation runs. The program can target individual files or folders, exclude them with wildcard rules, and operate through either a graphical interface or console command line. It can restart or shut down the computer after boot-time work. The listed compatible systems are Windows XP/2003/Vista/2008/7/8/10/11, including 64-bit versions; the page lists version 7.7.2, dated 07 December 2023.
