Explorer 95 Retro File Manager

Explorer95 lets you open multiple windows and do so much more than other file managers. The search engine lets you index your files quickly and performs instantaneous searches, you can decide when to rebuild the index.
The Apps view lets you sort your apps by name, or date installed, and there is a Launcher view as well.
Your usual Images, Videos, Audio, Documents, and Downloads file collections are viewable in detail and icon views, and feature Favorites per collection, and universally within Files.
Videos can have an "alias" which overlays over their icon in the display, so you can distinguish between different videos whose thumbnails look the same, and the alias can be found in the Search.
There's a text editor with configurable font size and keyboard style navigation buttons, an image editor with pixelart features, animated .gif layer support, with magic wand selection features, additive rectangular and circular marquee, and polygonal lasso.
The image viewer lets you choose between nearest-neighbor filtering for sharp low resolution image display and normal filtering, and has a fullscreen mode as well as a thumbnail grid display which is zoomable.
The video editor lets you record live keyframes of an overlaid image, moving it around, rotating it, and resizing it, to render the same video that you created.
And the audio player has playlists, playback speed changing, you can record with it, there's playback, recording, and monitoring device selection, and you can toggle monitoring on and off, and there's a spectrogram, and an oscilloscope visualization.
