exifmv

Moves images into a folder hierarchy based on EXIF tags.

Currently the hierarchy is hard-wired into the tool as this suits my needs. In the future this should be configured by a human-readable string supporting regular expressions etc.

For now the built-in string is this: {destination}/{year}/{month}/{day}/{filename}.{extension }

So if you have an image shot on Nov. 22. 2019 named Foo1234.ARW it will end up as this folder hierarchy: 2019/11/22/foo1234.arw.

Building

cargo build --release

Warning

With default settings exifmv uses move/rename only for organizing files . The only thing you risk is having files end up somewhere you didn’t intend.

But – if you specify the --remove-existing-source-files flag and it detects duplicates it will delete the original at the source. This is triggered by files at the destination matching in name and size.

In this case the original is removed!

However, you can use Rm ImProved by specifying the --use-rip flag. This requires aforementioned tool to be installed on your machine. When rip is used, files are moved to your graveyard/recycling bin instead of being permanently deleted right away.

All that being said: I have been using this app since about six months without loosing any images. As such I have quite a lot of empirical evidence that it doesn’t destroy data.

Still – writing some proper tests would likely give everyone else more confidence than my word. Until I find some time to do that: you have been warned.

Caveats For Developers

This is based on a Python script that did more or less the same thing and which served me well for 15 years. When I started to learn Rust in 2018 I decided to port the Python code to Rust as CLI app learning experience.

As such this app may not be the prettiest code you’ve come accross lately. It may also contain non-idiomatic (aka: non-Rust) ways of doing stuff. If you feel like fixing any of those or add some nice features, I look forward to merge your PRs. Beers!
