Defrag.exfat Is Inefficient and Dangerous

- The defragmentation algorithm is criticized as 'AI slop' due to its flawed logic.
- It relies on cluster swaps without traditional copy-update-unallocate steps, risking data corruption on power loss or process termination.
- Metadata commits are deferred until the last swap, increasing the risk of catastrophic failure.
- The algorithm is inefficient, moving all data to the leftmost side of the volume without optimizing for flash memory wear or runtime.
- No consideration is given to minimizing IO or keeping clusters contiguous, making it more of a data compaction than defragmentation.
- The process involves moving all data on the volume, regardless of necessity, which is highly inefficient for large volumes.
