STDU Explorer is a free file manager that lets you explore your files like Windows Explorer does. However, it provides a major improvement over Windows explorer as it lets you preview the file in Explorer Window itself. It shows files and folders in Left pane in tree structure. If you click on any file, STDU Explorer will show you preview of that file in right pane. This ensures that you can preview any file, before even opening it.
STDU Explorer is one of the best alterative to Windows Explorer. Windows Explorer can show preview of image files only. STDU Explorer however supports lot of file formats.
Here are some of the file formats supported by STDU Explorer:
- Image files like PSD, BMP, PNG, Gif, Pcx, Jpeg, Wmf, Tiff, and Multi-page Tiff.
STDU Explorer also lets you see preview of multiple pages together in a multi-page file. You just need to click on the file name in the Left pane, and STDU Explorer will show you preview of that file. You can even access tree structure of documents directly, so as to navigate within them.
Apart from previewing files, STDU Explorer also lets you perform other file operations. You can move files, rename files, delete, copy, and paste files. Basically, almost all the operations that Windows explorer supports.
STDU Explorer is completely free for non-commercial use, and is one of the best Windows Explorer alternative that I have come across. It comes from the makers of STDU Viewer.
