From the developer, “GSplit is a free file splitter that lets you split your large files into a set of smaller files called pieces, easier to copy to floppies, CD, DVD or any removable disk; distribute over the Internet, networks; send by email or with file hosting services; share with friends and colleagues. GSplit also generates small self-uniting programs when splitting files, so anyone even without GSplit may restore your split files automatically. GSplit can split very large files (larger than 4 GB) and it provides you with a lot of splitting options (in addition to five splitting methods, including functions for large text files like server logs). You can load/save settings into profiles, and also automate it. Finally it features an intuitive graphical user interface (with skin support) that makes operations easy and fast. Context-sensitive help and animated tutorials are also available.”
