Google Drive Duplicator

This project allows you to duplicate a complete folder structure from a Google Drive folder (shared or not) to your own Drive.

Features

• Recursive Copy: Copies all files and subfolders.
• Time Limit Management: Handles the 6-minute execution time limit of Google Apps Script. If the copy isn't finished, you can resume it, and it will pick up exactly where it left off.
• Verification: Compares the file count between the source and destination to ensure integrity.
• Google Sheets Interface: Easy control via a spreadsheet.

Installation

Option A: Copy-Paste (Simple)

1. Create a new Google Sheet.
2. Go to Extensions > Apps Script.
3. Delete existing code in Code.gs.
4. Copy the content of the src/Code.js file from this repository and paste it into the editor.
5. Save.
6. Reload your Google Sheet. A "Drive Duplicator" menu will appear.

Option B: Using CLASP (Advanced)

If you have Node.js installed:

1. Install clasp: npm install -g @google/clasp
2. Login: clasp login
3. Create a sheet: clasp create --type sheets --title "Drive Duplicator" (or clone an existing project).
4. Push the code: clasp push

Google Sheet Configuration

The script expects the following columns (order isn't strict, but headers help):

Row 1	A	B	C	D
Headers	Source Folder ID	Status	Destination URL	Verification

• Source Folder ID: The ID of the folder you want to copy (the part at the end of the folder URL).
• Status: Leave empty initially. The script will update it to "Pending", "Processing", "Done", or "Error".
• Destination URL: Populated by the script.
• Verification: Populated by the verification tool.

Usage

1. Fill in the Source Folder ID in column A.
2. Go to the menu Drive Duplicator > Start Copy.
3. If the script stops (time limit), the status will remain "Processing" (or indicate "Time Limit"). Simply click Start Copy again to resume.
4. Once finished, the status will be "Done".
5. To verify, click Drive Duplicator > Verify Folder.
