Key Features

Everything you need.
Nothing superfluous.

Ultra Explorer is engineered for power users handling massive data volumes: absolute simplicity, clarity, and control.

Peak Productivity

Two independent panels. Drag, drop, transfer.

The power of Total Commander and Finder combined for all your clouds.

Browse simultaneously in OneDrive and your local NAS, or between two separate S3 buckets. Ultra Explorer features multi-tabs, independent navigation history, instant filtering, and smart conflict resolution.

Drag & Drop Transfers

Drag files and folders across panes, from local to cloud or between two distant cloud endpoints.

Anti-Overwrite Protection

Zero silent overwrites: atomic validation and conflict prompts (Overwrite, Skip, Keep both).

Tabbed Browsing

Open as many exploration tabs as needed with saved paths and filters.

Frequently Asked Questions

Everything you need to know.

Questions regarding credential security, compatibility, or how syncing works?

rclone is the versatile open-source powerhouse to sync files to and from 40+ cloud storage providers. However, rclone operates from the command line. Ultra Explorer brings it the modern, intuitive GUI it always deserved: dual-pane explorer, drag & drop, dry-run safety previews, quota gauges, and disk space visualizer.
