The application has only been tested on Python 3.7.3 x86_64 on Windows. However, I don't see why it wouldn't work on *NIX as well. Note that Windows' default conhost terminal emulator may have problem displaying unicode characters. I personally run it in PyCharm CE or Visual Studio Code Terminal.

Create a virtual environment and activate it (optional / recommended)

python3 -m venv /path/to/new/venv
*NIX: source /path/to/new/venv/bin/activate
Windows: C:\path\to\new\env\Scripts\activate

Install dependencies requirements.
```
pip install -r requirements.txt
```
If you don't like to install packages to global/user scopes, you can also setup virtual environment
Navigate to conf/ directory and make a copy of each .sample.json files renaming each to remove .sample (ie, rename the copy to sync_settings.json).
Edit those files to populate the correct values.

Run the code

Run main.py in the terminal to start the application.

The program accept three optional positional parameters

Remote ItemID (such as 87654321012). This can be found on the URL when browsing on box.com website. User's root directory is 0. If not provided, will use jobs in sync_settings.json.
Local directory that will represent the remote directory. Leave empty or use . for working directory (not tested).

See --help for more information.

To change logging level, edit setup.py file.

When file conflict occurs, if the file size is different, the program downloads remote and overwrite local copy.

blacklist currently accepts path to file or directory with Unix shell-style wildcards, all relative to root of remote. The same blacklist currently apply to every drive root.

Explaining remote directory (to update)

For example

RemoteRoot of 87654321012
├───A
│   ├───A1.png
│   └───A2.png
├───B.jpg
└───C
│   ├───C1.png
│   └───C2.png
├───D.jpg
└───E
    └───E1.png

If the following blacklist is applied,

{
  "blacklist": [
    "A/A2.png",
    "C",
    "D.jpg",
    "E/E1.png"
  ],
  ...
}

the program will only concern these.

RemoteRoot of 87654321012
├───A
│   └───A1.png
└───B.jpg

Launching the program with ./main.py 87654321012 D:/BoxFolder will results in

D:
└───BoxFolder
    ├───A
    │   └───A1.png
    └───B.jpg

Launching the program with ./main.py 87654321012 D:/BoxFolder will results in

D:
└───BoxFolder
    └───A1.png

Note that the blacklist is still relative to remote root, not A.
