DriveGrab

Downloads every file of a public Google Drive folder (or a single file), keeping the folder structure. It needs no Google account or API key. The link only has to be shared as "Anyone with the link".

DriveGrab <link or id> [destination] [--list] [--parallel N] [--overwrite]

DriveGrab "https://drive.google.com/drive/folders/1wtLARgkGRZ_Dc84N4RZlX-JX_rxK0ADs" "D:\Hobby\LostKingdom\2026-10"
DriveGrab "https://drive.google.com/drive/folders/1wtLARgkGRZ_Dc84N4RZlX-JX_rxK0ADs" --list
DriveGrab "https://drive.google.com/file/d/<id>/view" D:\Downloads

Option
destination	the folder to download into (default: the current folder)
--list	lists the files with their sizes and the total; downloads nothing
--parallel N	how many files download at a time (default 4)
--overwrite	downloads again even when a file of the right size is already there

What it does

• Listing: it reads the whole folder tree from Drive's embedded folder view. That view lists every file; Drive's normal page shows only the first 50 in a folder. File sizes come from the folder pages, or from Drive directly for files beyond the first 50.
• Downloading: each file is written as <name>.part. When the size matches both the download and Drive's listing, the file is renamed. A broken download never leaves a half file under the real name. Each file gets 3 tries.
• Resuming: run the same command again. Files already there at the right size are skipped, so it only fetches what's missing or failed. Exit code 0 means everything is there.
• Names: characters Windows doesn't allow in names (\ / : * ? " < > |) become spaces. For example, "500 reward-Ojancano/Cuegle" becomes "500 reward-Ojancano Cuegle".
• Same names: Drive allows two files with the same name in one folder. The second is saved as "name (2).ext", the third as "name (3).ext", and so on.
• Google Docs, Sheets and Slides aren't files. They're listed as skipped.

Limits

• Quota: Drive limits how much one shared file can be downloaded per day. When it's exceeded, Drive sends a web page instead of the file. DriveGrab reports that file as failed (with the reason); try again later.
• Unofficial: it uses Drive's public pages rather than its official API, so a change at Google could break it. If listing fails on a link that opens fine in a browser, that's the likely cause.

Build

dotnet publish -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -o D:\Workspace\build\DriveGrab\publish

This gives DriveGrab.exe, a single file that needs the .NET 10 runtime. Or run it from source: dotnet run --project Tools\DriveGrab -- <link> [destination].
