dupEx VS Axcrypt

dupEx's answer

Its focus on the second half of the job: not just finding duplicates, but choosing safely which copy to delete. Information also lives in file names and folders, so dupEx pairs exact detection (hashing plus optional byte-for-byte verification) with selection rules, protected reference folders and live results that can be acted on while the scan is still running.

Linux desktop users with large, grown file collections — photos, documents, media archives, backups spread over several drives and NAS shares — and Linux power users who want exact control: byte-for-byte verification, regex selection rules, protected reference folders and network shares. Both want to reclaim space without the risk of deleting the wrong copy.

Axcrypt's answer:

• Personal users protecting documents like IDs, financial papers, medical files, and cloud backups.

• Professionals & freelancers who share confidential files with clients and need secure workflows.

• Small businesses & teams needing quick, dependable file-level encryption without enterprise complexity.

• Non-technical users who want strong protection but prefer a clean, simple interface.

dupEx's answer

It started in February 2026 as a hobby project: a way to compare large files bit by bit. During development, another tool reported two files as duplicates that differed in a single bit — if one copy is damaged, the intact one might be the one that gets deleted. That set the standard: dupEx has to be certain. What began as a tool for personal use grew into a product, tested on 13 Linux distributions, 7 desktop environments and 6 package formats before the stable 1.0.0 release in September 2026.

A C engine with BLAKE3 hashing, SIMD assembly for the byte-for-byte comparison (SSE2, SSE4.1, AVX2), OpenMP for parallel work and SQLite for the hash cache; libmagic for file-type detection; a GTK4 interface written in Rust (gtk4-rs).
