Ac Browser Plus Free Edition is a file manager for windows, with integrated image viewer and converter, FTP client, file finder, folder synchronizer, and encryption/compression/mass renaming tools.
Other features include for example ´editorial renaming´ (renaming files just like in a text editor), true multi-threading, calculating folder sizes ´on fly´, instant preview of image and multimedia files, file splitting and merging, simple script engine, zooming in/out thumbnails and other views (with Ctrl+mouse wheel), or file operation queueing.

The only difference between this release and its shareware counterpart is that the free version is unable to open more than 3 browse windows at a time.
