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:
- Getting a .csv file describing all duplicated files
- Comparing different file systems
- 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! :)
- Generate a duplicate file report for a path:
- dedupecopy -p /Users/ -r dupes.csv -m manifest
- Copy all .jpg files from multiple paths to a /YYYY_MM/.jpg structure
- dedupecopy -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 -p C:-p D:-c X:-m X:manifest -R *:no_change
- Resume an interrupted run (assuming "-m manifest" used in prior run):
- dedupecopy -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 -p \targetshare -m target_manifest dedupecopy -p \source1share -m source1_manifest dedupecopy -p \source2share -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 -p \source1share -c \targetshare -i source1_manifest--compare source2_manifest --compare target_manifest --no-walk
- dedupecopy -p \source2share -c \targetshare -i source2_manifest
- --compare source1_manifest --compare target_manifest --no-walk
Assuming you start with a set of files laid out as follows:
- photo1.jpg photo2.jpg
And you run the command: > dedupecopy -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):
- photo1.jpg photo2.jpg photo3.jpg
