Mp3Wrap

Mp3Wrap is a small command-line application whose purpose is to help you wrap two or more MP3 files into a single large item. It can be deployed on all Windows versions out there. The program is closely linked to Mp3Splt, another software utility created by the same developer, which allows you to split all your MP3 files.
In case you are familiar with inputting parameters in the CMD environment, you are going to control the entire merging process in no time. Less experienced users may find it a bit difficult to alter the dedicated parameters.
Mp3Wrap also reveals the supported functions and a few examples directly in the CMD environment. You can add user-defined files to an existing MP3 item, list the items wrapped in the output file, as well as display additional information about the merging task.
The utility is able to retain filenames and ID3 information. Plus, it offers you the possibility to include other files, such as playlists, info items, and cover images inside the current MP3 file.
You can take advantage of its portability status and drop it on pen drives or other portable devices. You do not have to go through an installation process because you can run the utility directly from the command-line console. You may get rid of it by deleting the files that you have downloaded from the Internet because it does not store entries in your Windows registry and leave other configuration files behind.
