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.

This is the Javascript equivalent of File Extension Fixer Rust.

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.
