File Extension Fixer

A tool that looks over every photo and video in a directory and corrects the file extension based off of the magic number of the file.

Cache

File Extension Fixer produces a cache file called .fixFileExt.sqlite in the directory that got passed as the argument to speed up execution for large directories if run again in the future. The cache file is a simple SQLite database containing a single column named file which can hold a VARCHAR of length 255 and includes a INDEX called idx_file for the file column to speed up searching for the file when checking the cache.

Usage

Building

bun run build

This only applies when wanting to run the project on the source directly without building it first.

Executing Standalone

This only applies when wanting to run the standalone script produced in the out directory once built.
