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
