Exclude folders and include subfolders

[jeromeroucou]

If a user wishes to upload a folder with a large number of files and a large tree structure, it would be useful to be able to exclude certain folders, while still being able to include sub-folders in excluded directories :

.
├── excluded_directory
│   ├── file_1.txt
│   └── included
│       ├── exc_folder
│       │   ├── file_3.txt
│       │   └── include
│       │       └── file_4.txt
│       └── file_2.txt
└── file.txt

In the example above, the user wishes to upload only the files file.txt, file_2.txt, and file_4.txt.
