Directory Checksum Manifest Verifier is a recursive folder integrity workbench, bit-rot auditor, and directory tree comparator for backups, removable media, and project archives. Designed as an independent Linux desktop alternative to CDCheck and SFV manifest utilities, it generates and audits standard digest manifests across whole directory hierarchies while measuring real storage read throughput.

Key Features:

• Multi-Format Manifest Generation & Auditing: Creates and verifies .sha256, .sha512, .md5, and .sfv (CRC32) manifest files across recursive directory trees using standard coreutils and Simple File Verification text layouts.
• Four-State Folder Audit Classification: Audits target folders against manifest files and flags every item as OK, MODIFIED, MISSING, or UNLISTED with expected versus computed digests.
• Direct Two-Directory Tree Comparison: Compares any two folder trees side-by-side by size and content digest to pinpoint identical, modified, missing, and extra files.
• Read Throughput & Audit Reports: Measures real disk read speed in MB/s during file reads and exports structured CSV and JSON verification reports.
