Batch File Split & Join - Split and merge multiple text or binary files in either character, line, or byte modes. When splitting files, you can split on certain text or binary separator; target given number of parts; or target specific part size. In all cases you can select operational unit to be either line or character for text files and byte for data/binary files. Files can be joined in specific order on a line-to-line, char-to-char, or byte-to-byte level.
