The concept of unfurling is to take all items from within a given tree and move them as far up the tree as possible.

folder
└───subfolder1
│   └───subfolder2
│   │   └───subfolder3
│   │   │   │   file.txt
│   │   │   └───subfolder4
│   │   │   │   │   file.txt

Should end up turning into something looking like using a respectful unfurl:

folder
│   file.txt
└───subfolder4
│   │   file.txt

Or, by using a non-respectful furl:

folder
│   file.txt
│   file.txt

Because this program uses the docopt library, to use this program you have to install the library by running:

pip install docopt==0.6.2

• unfurl -h or unfurl --help - Show program help
• unfurl -v or unfurl --version - Show program version
• unfurl -r or unfurl --respect - Respect the tree structure
• unfurl <folder> - Unfurl everything in given folder only
  • EG: unfurl asdf

Why does Destination path 'C:\Users\user\folder\asdf' already exists occur when there is no file/folder with the same name?

Python does not see a difference between files and folders; therefore - it is impossible to move a file to a directory where a folder has the same name.
