Advanced File Joiner combines files. If you have downloaded several parts of a larger file split in smaller files you may join them together with the help of this tool. It works with plain ASCII text files, merges some movie file formats like MPEG files of the same size, format and encoding. If the file format that you are trying to join contains header information, such as AVI, BMP, JPEG, DOC then it will not work, you have to use a specific software join program for each of the above formats.
