Windows batch – concatenate multiple text files into one

Windows type command works similarly to UNIX cat.

Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv)

type file1.csv file2.csv > concat.csv

Example 2: Merge files with pattern (This will merge all files with csv extension and create concat.csv)

When using asterisk(*) to concatenate all files. Please DON’T use same extension for target file(Eg. .csv). There should be some difference in pattern else target file will also be considered in concatenation

type  *.csv > concat_csv.txt
