You can use the Windows type command to combine more than one file, if that was previously typed in. It will overwrite the existing one, so if it's the first file you entered, you'll have to make a copy of it first. To see how all the operations are done, see what it looks like this way: The type command looks like this: type newfile.txt is the original text files (one and the same folder where the first text file is); newfile1.txt is the first text file concatenated into newfile.txt newfile2.txt is the second text file concatenated into newfile.txt Newfile1.csv is the spreadsheet where you entered a text file containing two columns, and you want it to be concatenated to newfile.txt newfile2.csv is the spreadsheet where you entered a text file containing two columns and you want it to be concatenated to new file.
