OneDrive Crypto Uploader — v1.2 (Search + Breadcrumbs + Smart Save Name)

Cross-platform Qt 6 / C++20 GUI that encrypts files locally, uploads encrypted files to OneDrive (Microsoft Graph), and downloads + decrypts them.

What’s new in v1.2

✅ Search box (filter current folder list)

• A search field filters the current folder table client-side via QSortFilterProxyModel.

✅ Clickable breadcrumb bar

• Breadcrumbs show your navigation path.
• Click any crumb to jump back to that folder.
• Up now goes to the parent crumb (not just root).

✅ Smart “Save As…” decrypted filename

• After downloading downloaded.odenc, the app reads ODENC metadata (original plaintext name) and proposes it as the default output filename.
• You can still pick any filename/location using a Save dialog.
