SharpFile

SharpFile is a simple-to-use file manager that supports multiple tabs and lets you perform common file operations. It doesn't require installation and contains intuitive options that even less experienced users can figure out properly, such as preview and command-line embedded windows.
Before proceeding any further, you should know that this app hasn't been updated for a pretty time and, although it seems to work on newer Windows editions, some of its features may have compatibility issues on modern OS configurations. For instance, drag-and-drop is supposedly supported by SharpFile for easily copying files from one pane to the other. However, this didn't work on Windows 7 in our tests, even with administrative privileges enabled.

Multi-tabbed dual-pane file manager

The user-friendly interface is represented by a standard window with a clear-cut structure, where two panes give you the possibility to visit different locations on the disk and easily perform file transfers between them. Each pane supports multiple tabs, so you can cycle through as many different directories as you want.

Perform basic file management operations

You can check out the name, size, date and time of each file and folder, as well as filter items by file type. Moreover, it's possible to disable any of the panes or switch to horizontal view mode, swap panes, disable the previewer and command line window, as well as launch a Command Prompt instance in the current location. The file operations available are the ones from Windows Explorer, since SharpFile mimics its right-click menu.

Evaluation and conclusion

No error dialogs popped up in our tests and the software utility didn't hang or crash. It had minimal impact on computer performance, running on low CPU and memory. However, we expected richer options and customization preferences that would surpass Windows Explorer. We must also keep in mind that SharpFile hasn't been updated for a long time. You can test it for yourself, though, since it's free.
