UnPacker is a simple-to-use application which allows you to extract files and folders from archives. It supports the RAR and ZIP formats, and can be handled even by inexperienced users.
The interface of the program is based on a standard window and a simple-to-follow layout. You can start a new extraction task by selecting a directory, in order to scan it for archives; this can be seamlessly done, with the courtesy of the Explorer-based layout.
UnPacker can take a while to finish a scanning job, depending on the size of the specified target. All results are displayed in a separate window where you can select which archives you want to perform the extraction procedure on. It is possible to create an unpack queue and schedule multiple archives for processing.
Additional features of UnPacker let you hide windows (e.g. of scans or found items, the toolbar), view log details, customize the toolbar, minimize the program to the system tray area, specify the thread priority, pause tasks and save the queue for further processing.
From the Settings screen you can enable the options to clear the scan before searching, get archive information when it's added, trigger a flashing effect when all extraction jobs are completed, and to remove empty directories. But you may also specify the levels for logs and message confirmations.
The simple-to-use application is pretty low-demanding when it comes to the CPU and system memory, so it doesn't interfere with the runtime of other currently active processes. It has a good response time. No error dialogs have been shown in our testing and UnPacker did not hang or crash. On the other hand, the tool can take a long time to go through directories when searching for archives, and there is no method to skip this step, such as handing out a specific archive item to it. We must take into consideration the fact that UnPacker has not been updated for a long time.
