Windows File Explorer Portable-Read the FULL POST to make sure you get everything you need.
Windows File Explorer is a regular file explorer, like Windows Explorer, but with many more options such as two panels, file previews, and more. The application is also free, but not open-source. I decided to make a launcher for it anyways because it my personal opinion, it's a fairly decent file browser.
Since freeware apps are not allowed here currently, I have only made a launcher for Windows File Explorer. You will have to download and install the actual application yourself with a mirror I will provide.
Install it to WindowsFileExplorerPortable\App.
Now run the executable (WindowsFileExplorerPortable.exe) and it should work.
Note: I have been informed that on first run, this will erase your current settings for local install of this program, but from then on, your settings will stay separate for both, I am looking into it.
