Application · File manager / Android · 2026
Files, RAW photos and your NAS in one workspace with folder tabs.
An Android file manager with folder tabs, SMB access to a NAS, a gallery with RAW support and a histogram, and folder sync with a NAS, SD card or USB drive.
Internal storage, SD cards, system folders and SMB shares open in independent tabs, with breadcrumbs and a folder tree. Operations come with a restorable trash, name-conflict prompts and background transfers showing speed and progress.
The gallery reads RAW files from over a dozen camera makers and shows an RGB histogram, a clipping mask and EXIF data, while session mode watches a folder live – new shots from a camera or Wi-Fi card appear immediately. On a tablet the side panel and property inspector stay visible.
