DedupeCopy 0.3.6

Find duplicates / copy and restructure file layout command-line tool

Latest Version: 0.3.8

Find duplicates / copy and restructure file layout command-line tool.

This is a simple multi-threaded file copy tool designed for consolidating and
restructuring sprawling file systems.

The most common use case is for backing up data into a new layout, ignoring
duplicated files.

Other uses include:
1. Getting a .csv file describing all duplicated files
2. Comparing different file systems
3. Restructuring existing sets of files into different layouts (such as
sorted by extension or last modification time)

This tool is *NOT* a Robocopy or rsync replacement and does not try to fill
the role those play.

As with all code that walks a file tree, please use with caution and expect
absolutely no warranty! :)


Command examples:

Generate a duplicate file report for a path:
dedupecopy.py -p /Users/ -r dupes.csv -m manifest

Copy all *.jpg files from multiple paths to a /YYYY_MM/*.jpg structure
dedupecopy.py -p C:\pics -p D:\pics -e jpg -R jpg:mtime -c X:\pics

Copy all files from two drives to a single target, preserving the path for
all extensions:
dedupecopy.py -p C:\ -p D:\ -c X:\ -m X:\manifest -R *:no_change

Resume an interrupted run (assuming "-m manifest" used in prior run):
dedupecopy.py -p /Users/ -r dupes_2.csv -i manifest -m manifest

Sequentially copy different sources into the same target, not copying
duplicate files (2 sources and 1 target):
1.) First record manifests for all devices
dedupecopy.py -p \\target\share -m target_manifest
dedupecopy.py -p \\source1\share -m source1_manifest
dedupecopy.py -p \\source2\share -m source2_manifest

2.) Copy each source to the target (specifying --compare so manifests from
other sources are loaded but not used as part of the set to copy and
--no-walk to skip re-scan of the source):
dedupecopy.py -p \\source1\share -c \\target\share -i source1_manifest
--compare source2_manifest --compare target_manifest --no-walk
dedupecopy.py -p \\source2\share -c \\target\share -i source2_manifest
--compare source1_manifest --compare target_manifest --no-walk


Complete example:

Assuming you start with a set of files laid out as follows:

C:\
pics
some_photos
photo1.jpg
photo2.jpg
photo3.jpg
D:\
pics
copied_photo
photo3.jpg
photo4.jpg

And you run the command:
> dedupecopy.py -p C:\pics -p D:\pics -e jpg -R jpg:mtime -c X:\photos

You would end up with the following (photo3.jpg was a true duplicate):

X:\
photos
2012_08
photo1.jpg
photo2.jpg
photo3.jpg
2012_09
photo4.jpg
