Ghin Explorer

Ghin Explorer is a file navigator written in Java, which lets you perform simple file management operations. It doesn't include advanced options or configuration settings, so it's mostly targeted at beginners.
Before proceeding any further, you should know that this application hasn't been updated for a long time, so you may experience stability issues on newer Windows versions.

Easy installation and plain GUI

Setting up this tool is an easy job and the only notable aspect about it is that you need Java installed.
As far as the interface is concerned, Ghin Explorer adopts a standard window with a clear-cut structure, where you can explore a hierarchical view of the disk directories and view files.

Basic file management operations

It's possible to filter files extension (ZIP, Java, Java archive, text, executable, document, spreadsheet, HTML), copy them to other locations, remove them from the disk, rename them, as well as to open them with the default drawing, text, word or spreadsheet editor, web browser, or Java runtime.
Moreover, you can create new files or folders in the current location, view file properties (last access time, size, location), use buttons to easily go forward and background, use a quick search function, select a different drive or directory from a drop-down menu, as well as change the viewing mode.

Performance results

The utility worked smoothly throughout our evaluation, without hanging, crashing or prompting error messages. As we expected, it didn't put a strain on the overall performance of the machine, as it needed low CPU and RAM to work properly. On the other hand, it comes equipped with only a few standard file management options.

Conclusion

Too bad that it hasn't been updated for a long time. Nevertheless, you can test Ghin Explorer for yourself if you're looking for a simple and straightforward file manager without worrying about complicated customization preferences.
