Manage S3-Compatible Storage
like a local drive

A desktop file manager for S3-compatible object storage. Browse, upload, download, and organize files with a familiar interface — no CLI needed.

Everything you need for object storage

S3 File Manager gives you a visual interface to manage your Spaces buckets without memorizing AWS CLI commands or writing scripts.

🔒

Encrypted Credentials

Access keys are encrypted by your operating system's secure storage. Your credentials are never stored in plain text.

📁

Bucket & Folder Navigation

Tree sidebar for fast bucket switching. Breadcrumb trail, back/forward history, and double-click navigation — just like Finder or Explorer.

Upload & Download

Drag-and-drop uploads with support for large files. Batch download multiple files at once. Background transfer queue with real-time progress.

👁

File Preview

Preview images, video, audio, PDFs, and code files directly in the app. Syntax highlighting for 20+ programming languages.

Full File Operations

Rename, copy, move, delete with confirmation dialogs. Create folders. Calculate folder sizes recursively.

🔗

Presigned URLs

Generate time-limited public download links for any file. Configurable expiry. One-click copy to clipboard.

👤

Multiple Profiles

Save credentials for multiple Spaces regions or accounts. Switch between them in one click without re-entering credentials.

Light & Dark Mode

Toggle between themes from the toolbar. Preference is saved and restored on next launch.

Keyboard Shortcuts

Power-user shortcuts for every common action — select all, upload, download, rename, delete, navigate. No mouse required.
