Click on the folder to open it.\n3.  Look at the URL in your browser's address bar. The Folder ID is the long string of characters at the end of the URL.\n\n**Example:**\nIf your browser URL is:\n`https://drive.google.com/drive/folders/`**`1Fs3gg7pSVhbvODJQLcgAfP-V0rCGC_Oc`**\n\nThen your Folder ID is:\n**`1Fs3gg7pSVhbvODJQLcgAfP-V0rCGC_Oc`**\n\nCopy this ID and paste it into the `parentFolderId` field in the **\"CONFIG - Set your variables here\"** node."

It keeps the most recent ones (you can define how many) and deletes all the older folders.\n* **Creates Daily Folders**: It creates a new, neatly named folder in your Google Drive for each day's backup (e.g., `Workflows backup - 2025-08-17`).\n* **Fetches and Saves**: It connects to your n8n instance via API, fetches all your workflows, and saves each one as a `.json` file inside the daily folder.\n\n## How to set up\n1.  **Configure Credentials**: Make sure you have valid credentials for:\n    * **n8n API**: To allow the workflow to access its own list of workflows.\n    * **Google Drive**: To allow the workflow to create folders and upload files.\n2.  **Set Your Variables**: In the first `Set` node named **\"CONFIG - Set your variables here\"**:\n    * `parentFolderId`: Paste the ID of the main Google Drive folder where you want all your daily backup folders to be stored.\n    * `backupsToKeep`: Set the number of recent backups you wish to keep (e.g., 30 for a month's worth).\n\nActivate the workflow, and you're all set!"
