>Split File.
A – Select “File” from the menu
B – Select “Split File”
Once you click “Split File…” 7-Zip will bring up a window asking you the directory you want to split the file to and what size you want each part (7z/RAR) to be.
A – Select the desired size for each part of the archive.
B – Click “OK”
After you selected the file size in the drop down menu, 7Zip will split the files into parts of the selected size. A Status window will appear showing you the process.
When complete, the files will be in the designated folders that you specified during the beginning of the process.
