About Sigma
Sigma File Manager is a file manager (explorer) app for Windows and Linux, offered on its homepage as free and open-source. It covers everyday file work: searching with filters by name, type and date modified, moving files by drag and drop, browsing two locations side by side in dual pane view, and previewing images, videos and documents in a built-in viewer. It also compresses and extracts archives such as ZIP and RAR, and lets users adjust color schemes and layout options.
The homepage states that an Alpha v2 release is out, and downloads are offered through GitHub. Cloud storage accounts such as Dropbox, Google Drive and OneDrive can be connected, which means file access through those integrations depends on the third-party services involved.
