Concatenate Data is a CSPro tool that allows you to concatenate (that is, join end-to-end) two or more CSPro data (or other text-based) files. You do not need a dictionary for this utility, you only need to know the name and location of the files you wish to combine.
Concatenate Data is found on the CSPro Tools menu under "Concatenate Data." To start the concatenation process, select this option from the menu.
