TwinFiles

TwinFiles is a file manager app that lets you open different folders in two panes, one on the top and one on the bottom, so you can organize files while comparing them side by side vertically.
You can browse photos, videos, audio files, PDFs, folders, and more in a clear list, making it easier to find the files you need or move them to another folder. By using the top and bottom panes separately, you can work more smoothly while viewing both the source and destination folders.
Main features:
Dual-pane file management
File and folder browsing
Drag and move with a 0.3-second long press
Image preview
File sharing
Favorite folders
Recent files
Sort by name or date
Display language switching, including Japanese and English
The free version includes the basic dual-pane file management features. With the PRO version, you can unlock more powerful organization tools, including unlimited favorites, unlimited multi-select, recent files from the past month, sorting by size and type, batch copy/move, rename, ZIP/compress and unzip, smart organize, duplicate detection, search, filters, thumbnail display, theme changes, and more.
TwinFiles is designed for people who want to organize files on their device, manage photos and videos by folder, or work while comparing two locations at the same time.
