How Kickass Undelete Restores Your Files

When you delete a file in Windows, the actual data remains on your drive until it gets overwritten. Kickass Undelete scans these unallocated sectors and helps you bring your data back in 4 simple steps.

Crucial Tip for Data Recovery: To prevent overwriting your deleted files, do not download or extract Kickass Undelete onto the same partition where your lost files were stored. Save it to an external USB drive instead.

Known Limitations & When to Use Alternatives

While Kickass Undelete is ideal for quick file recovery on FAT and NTFS drives, certain complex recovery scenarios require advanced algorithms or different file system support.

Technical Limitations

  • No exFAT Partition Support: Modern large USB drives and high-capacity SD cards using exFAT are not supported.
  • Basic Index Scanning Only: Lacks deep raw-sector carving for formatted drives or heavily corrupted file structures.
  • Windows OS Exclusive: Cannot run natively on macOS, Linux, or mobile operating systems.
  • Legacy Software Status: Official development has ended (v1.5.5 is the final release).

Frequently Asked Questions

Get clear answers to common questions regarding Kickass Undelete, its capabilities, and data safety.

Is Kickass Undelete safe to use?

Yes, Kickass Undelete is completely safe. It is an open-source software distributed under the GNU General Public License v3 (GPLv3). It contains no malware, spyware, or bundled third-party adware. Because it operates in read-mode during scanning, it will not corrupt your storage drive.

Does Kickass Undelete support exFAT or APFS drives?

No. Kickass Undelete is specifically designed for Windows file systems and supports FAT (FAT12, FAT16, FAT32) and NTFS partitions only. It does not natively support exFAT, ext4, or macOS file systems like APFS or HFS+.

Why can’t Kickass Undelete find my lost files?

If Kickass Undelete cannot detect your deleted files, the file allocation table or master file table entries may have been overwritten by new data, or the disk partition may be severely damaged (RAW format). For heavily corrupted partitions or unsupported exFAT drives, a deep raw-sector commercial recovery tool may be required.

Do I need to install Kickass Undelete on my PC?

No installation is required. Kickass Undelete is provided as a standalone portable executable file (KickassUndelete_1.5.5.exe). You can run it directly from a USB flash drive or external hard disk.
