This is the portable version of EF Duplicate Files Manager, an application designed to help you locate and remove duplicates from your computer, in order to free up space.

Since installation is not required, you can place Portable EF Duplicate Files Manager on a removable device (like a USB flash drive), plug it into any computer and directly run its executable file. What's more important is that your Windows registry keys will remain intact.

The interface of the program is plain and simple to work with. You can get started by selecting the folder or volume to look into, and proceed with the scanning task.

Once results are displayed, you can check out the name, size, date of modification, attributes, location and type of each file. The groups of duplicates are color-coded, so you can easily identify them.

If you access the "Options" area, you can filter your search (e.g. same name, size or content, skip zero-length files, exclude folders). But you can also enable Portable EF Duplicate Files Manager to select all duplicates, sort items (e.g. by name, extension, time), copy, move, rename and delete files, export the list, view file properties, customize the toolbar, and more.

The simple-to-use program requires a low amount of system resources, quickly finishes a scan job, includes a well-drawn help file with snapshots and didn't freeze, crash or pop up errors during our tests. Putting aside the dull interface, we strongly recommend Portable EF Duplicate Files Manager to all users, regardless of their experience level.
