Directory Duplicator (formerly DirDup)

For those who need to transfer information between computers on a regular basis, copying files and folders accurately and quickly is important, but can also be difficult. Directory Duplicator is an application that tries to eliminate most of the common problems with copying entire directories and drives.

A simple and easy-to-use interface that is straightforward to operate and streamlined for regular use

Directory Duplicator is clearly developed by someone who intended to use it themselves as it is provides a very efficient interface that is born of experience. Users can select a directory to copy, however large, and the program offers options to optimize the process.
Once the copying process begins, any problems or incomplete transfers are noted in an error log on the main window, clearly displaying what went wrong and what particular file is incomplete. The size of the directory, number of files and the date are all clearly marked, enabling users to organize themselves efficiently and prevent a duplication of work.

Useful features that help users transfer large numbers of files or entire directories effectively

Given that Directory Duplicator is designed to be used as a backup tool, especially for flash drives, it includes a number of settings to make that process easier. Users can pick between two distinct modes, quick and full copy, which offer different levels of control. Depending on which setting is selected, the application can automatically validate files, not copying files that already exist on the portable device.
Along with the automatic date and file size comparison, users can exclude specific files and folders from being copied to speed up the process, and only backup essential files. The Full copy mode goes further, by ignoring dates and sizes, and doing a byte by byte comparison, checking for any data deterioration. On top of these features, the program also fully supports command lines, allowing Directory Duplicator to be scripted to perform additional functions.

A comprehensive, customizable tool that does its best to optimize large scale copying between devices

All in all, Directory Duplicator is a very useful application for those who find themselves regularly transferring information to flash drives. The program goes to great lengths to make the process as efficient as possible and stop any wasteful actions. Any user who feels that Directory Duplicator might help backing up projects or drives to a portable device will not be disappointed.
