Here’s a clean Markdown “Additional info” you can paste into GreasyFork:
Claude Project Downloader (NEW)
One-click downloader for all files in a Claude project.
Supports both previewable text files and non-previewable/binary files (e.g., .xlsx, .pdf, images).
✨ Features
- One click: Scrapes the current project’s Files panel and downloads everything.
- Text & Code: Captures the full visible preview for text/code files.
- Binary Files: If Claude can’t preview (e.g., “File previews are not supported for this file type”), the script:
- Finds a Download link and fetches the actual bytes into the ZIP.
- If cross-origin (CORS) blocks the fetch, it adds a
.url Internet Shortcut pointing to the file so you still have a working link.
- Nice UI: Floating “Download project” button + progress modal.
- Safe filenames: Cleans invalid characters for ZIP entries.
🛠 How to Use
- Open a Claude project that has files in the right-side Files panel.
- Click “Download project” (bottom-right floating button).
- Wait for the modal to reach Done — your browser saves
claude_project_files.zip.
Tip: Leave the Files panel scrolled to the top so all tiles are easily detected.
🔒 Permissions
This userscript loads two small libraries:
fflate (for ZIP creation)FileSaver.js (for saving the ZIP)
It also uses @connect * to let the browser download file bytes if the file host requires same-session cookies.
Privacy note: The script runs locally in your browser, only on https://claude.ai/*. It does not send your files anywhere.
⚠️ Known Limitations
- Some hosts block cross-origin downloads even with session cookies.
When that happens, the ZIP will include a
<filename>.url pointer you can open directly to download the file.
- Claude’s DOM may change over time. If the button doesn’t appear or files are skipped, please report with a screenshot of the open file viewer.
🧰 Troubleshooting
- Binary not included? Check inside the ZIP for a
.url file (CORS fallback).
- No files found? Ensure you’re on a project page and the Files panel shows file tiles/cards.
- Popup blocked? Allow downloads/popups for
claude.ai.
- Corporate blockers? Some extensions/security tools interfere with cross-origin fetches. Temporarily disable and retry.
📦 What’s Inside the ZIP
- Text/code files → saved as the original file name with their full preview content.
- Binary files (e.g.,
.xlsx, .pdf, images) → actual bytes when fetchable.
- If blocked by CORS → a
<name>.url Internet Shortcut pointing to the original asset.
🗂 Changelog
v1.1
- English UI and messages.
- Binary support: fetch bytes for non-previewable files (e.g.,
.xlsx).
- CORS fallback to
.url pointer.
- More robust selectors; no hard-dependency on a single preview class.
v1.0
