Sometimes we need to transfer a big chunk of files from one PC to another PC and to do this, at times, we need to split the file into smaller pieces in order to fit it on a CD/DVD, or send it via email. There is a lot of file splitter software available online that can split a file equally by number and cut any segment of the file as needed. I usually use the rar software as a file splitter.

When you rejoin the file that you split into the original file there are times that by doing this windows can’t open files with File Extension 1. The file extension 1, in this case, is a File Splitter that splits a file into smaller parts. If Windows is unable to open files with File Extension 1, you may not have the appropriate program installed or, you may have registry errors. By downloading the free drivers detective this can help to fix the error.
