To install, you need a working Python environment with pip. Then clone this repo and in the root run:
PBR_VERSION=1.0.0 python -m pip install .
There are a bunch of command line arguments that will control the behavior; use:
photorger --help
to see them. There are four main commands: info, move, clean and unshadow, to get EXIF info, move files into folders based on creation date, remove duplicates, and make case-sensitive files safe for non-case-sensitive file systems, respectively. clean and move can be destructive and result in the loss of files for which I take no responsibility; use at your own risk. You can use --pretend to see what actions would be taken in a trial run. It should be the case that at the very least no file will be deleted unless there is at least one byte-for-byte duplicate elsewhere, but I make no guarantee of that claim. I will say that I used this on my own photo collection with no problem and created an ordered collection of about 50,000 photos from a disordered collection about 10x that size with numerous duplicates from different backups over the years with different file naming conventions, in a few hours.
photorger info <fname>
will dump EXIF tags from a file.
photorger clean --source=<folder> --dest=<folder>
will remove any files in the source folder that have duplicates in the dest folder. The source and dest folders can be disjoint, or the source folder can be a subfolder of the dest folder.
photorger clean --source=<folder>
is similar but searches just a single folder tree, and in this case if it finds a set of duplicates it will keep the file(s) that are in folders with a YYYY/MM/DD format; this behavior can be changed with other arguments. After running this with no argument or with the arguments you prefer, you will likely still have duplicates, but you can run it again with a --force argument which will then use lexical ordering on the file paths to determine a single file in each duplicate group to keep, eliminating all other duplicates.
photorger move --source=<folder> --dest=<folder>
will try to figure out the dates photo files in the source directory were taken and move them to folders of the form YYYY/MM/DD/fname in the dest directory (both arguments are optional and will default to the current working directory). It will use EXIF tags if present, else will try infer the date from the file name. If it tries to move a file and the target file already exists, it will just delete the source file (if identical) or move and rename it (if not identical).
It can move files across file systems; if a simple rename fails it will fall back to copy/delete.
photorger unshadow --source=<folder>
will look for files in the same folder that have the same name and differ only in letter case and will rename files as necessary so that when used in a case-insensitive fashion (e.g. as an SMB mount) the files will not shadow each other but be seen as distinct.
This script currently works for Unix-style paths only, so Mac/Linux and not Windows.
I take no responsibility for any loss or damage from using this script. Use --pretend until you have some confidence that it is not going to ruin your life.
