What features does Sigma File Manager offer?

Sigma File Manager is a free, open-source file manager (explorer) app for Windows and Linux, and its feature set centers on search, file organization, previewing, archiving, and interface customization. The features below come from the project's own site, so treat them as the vendor's description rather than independent testing. The app is currently labeled an Alpha v2 release, which is worth knowing before you rely on it for critical file work.

Search and file organization

Advanced file search

The site describes a powerful search function that lets you find any file or folder and filter results by name, type, date modified, and more. In practice, this means you can narrow a large directory down to, for example, only images modified in the last week without opening each folder.

Drag and drop

Files and folders can be moved by dragging and dropping within the app. You can rearrange, copy, or transfer files between directories this way, which is the standard interaction most users expect from a file manager.

Dual pane view

A dual pane view lets you browse and manage two different locations at the same time. This is useful for tasks like moving a batch of files from a download folder into a project directory while keeping both visible.

Viewing and handling files

Built-in file viewer

You can preview files without opening an external application. The site lists images, videos, documents, and more as supported preview types, so you can check a file's contents before deciding what to do with it.

Archiving and compression

Sigma File Manager can compress and extract files in archive formats such as ZIP and RAR. The site frames this as a way to save storage space and share files conveniently, and it means you may not need a separate archiving tool for common formats.

Interface and integration

Customizable interface

The appearance can be tailored with different color schemes and layout options, so you can adjust the look to your preferences.

Cloud storage integration

According to the site, you can connect cloud storage accounts such as Dropbox, Google Drive, and OneDrive to the app. The site does not detail how the connection works or what limits apply, so verify this in the app itself if cloud access is central to your workflow.

Quick reference

Before you try it

• Platforms: Windows and Linux, per the site's FAQ.
• Cost and licensing: Described as free and open-source; downloads are directed to GitHub.
• Maturity: The site announces an "Alpha v2" release, so expect the feature set to change quickly. Test it on non-critical files first, especially if you plan to use it for archiving or moving large batches.
• Verification: The feature list above is the project's own description. If a specific capability (such as RAR extraction or a particular cloud provider) is essential to you, confirm it in the installed app before switching over.
