# This class is used by Import/Export to move files and folders from a source folders into a target folders
|
|
# that can already have the same folders in it, resolving in a merged folder.
|
|
#
|
|
# Example:
|
|
#
|
|
# source path
|
|
# |-- tree
|
|
# | |-- project
|
|
# | |-- labels.ndjson
|
|
# |-- uploads
|
|
# | |-- folder1
|
|
# | | |-- image1.png
|
|
# | |-- folder2
|
|
# | | |-- image2.png
|
|
#
|
|
# target path
|
|
# |-- tree
|
|
# | |-- project
|
|
# | |-- issues.ndjson
|
|
# |-- uploads
|
|
# | |-- folder1
|
|
# | | |-- image3.png
|
|
# | |-- folder3
|
|
# | | |-- image4.png
|
|
#
|
|
# target path after merge
|
|
# |-- tree
|
|
# | |-- project
|
|
# | | |-- issues.ndjson
|
|
# | | |-- labels.ndjson
|
|
