 1 | # google-drive-downloader
 2 | Batch download files from Google Drive
 3 | 
 4 | ## How To Use
 5 | 1) Setup Python on your system
 6 | 2) Create a new [Google Drive project](https://developers.google.com/drive/activity/v1/guides/project)
 7 | 3) Create an OAuth 2 Client ID from [here](https://console.developers.google.com/apis/credentials) and download the resulting json file. Rename it to  `client_secret.json`
 8 | 4) Move both the scripts from this repo and the downloaded json file to a single directory
 9 | 5) Open `create_download_list.py` and replace `Enter folder ID here` with the folder ID you want to download
10 | 6) Save and run `create_download_list.py`
11 | 7) If you are running the script for the first time, it will open your browser window and ask you to grant permissions to you app. Click on `Advanced` and proceed to grant the permission. Re-run `create_download_list.py`
12 | 8) You will end up with `filesList.txt` in your current directory. You can modify this file to remove the files you don't want to download
13 | 9) Run `download_files.py` and wait for the download to complete!
