Cosmil is a file manager and Finder alternative for macOS designed around flexible multi-pane workflows, fast navigation, and a customizable interface. Its translucent, glassy design integrates with the macOS desktop while providing additional tools for managing local, cloud, and remote files.
Features
- Flexible multi-pane layouts: Add and remove panes as needed to work with several folders or locations in the same window, with support for tabs and keyboard-driven navigation.
- Remote locations: Connect directly to FTP, SFTP, SMB 2/3, and WebDAV servers, including NAS devices and other network storage.
- Remote file editing: Open remote files in other Mac applications and automatically upload saved changes back to the connected server.
- Cross-location transfers: Copy and move files between local folders, mounted volumes, cloud storage, and remote servers, with transfer progress available through the job manager.
- Cloud storage integration: Access providers such as iCloud, Dropbox, and OneDrive from the sidebar, with support for cloud file download and eviction states.
- Fast large-folder browsing: Virtualized file views and optimized directory loading help keep navigation responsive in folders containing large numbers of files.
- Native macOS integrations: Uses macOS file icons, Quick Look previews, the system Share menu, Open With support, and familiar drag-and-drop behavior.
- Customizable list view: Resize and reorder columns, sort by multiple file properties, and configure date formatting and other appearance preferences.
- Search: Search files with streamed results and navigate results without waiting for the entire search to finish.
- Custom themes: Adjust Cosmil's color palette, create separate light and dark appearances, and import or share theme files.
- File-management tools: Create files and folders, duplicate items, create symbolic links, calculate file sizes, resolve transfer conflicts with complete file metadata, and view storage usage for mounted volumes.
- Keyboard-focused workflows: Includes shortcuts for switching panes and tabs as well as F5/F6 copy and move operations between panes.
Cosmil is intended for Mac users who want to manage several locations within a single workspace while retaining familiar macOS behaviors and integrations.
