How to merge or combine multiple files
Here is how to merge a text (.txt) file in the Windows command-line (cmd.exe) environment.
In your Windows cmd.exe command-line, use the following single command to merge all text files in a directory into one new file:
copy /b *.log newfile.logCode language: PowerShell (powershell)copy /a *.txt newfile.txtCode language: PowerShell (powershell)The copy parameters /a and /b indicate ASCII text or BINARY files.
Concatenate two text files in PowerShell?
In PowerShell you can use the Get-Content and Set-Content cmdlets to concatenate two (or more) files into one new file. For example:
Get-Content *.log | Set-Content newfile.log
# Get-Content logfile1.log, logfile2.log, logfile3.log | Set-Content newfile.logCode language: PowerShell (powershell)This is ideal for combining multiple log files into one file for LogParser and IIS log forensics.
You can use Python for this job, as below:

import shutil
import os
import glob
filenames = glob.glob(‘*.txt’)
with open(‘output_file.txt’,’wb’) as wfd:
for f in filenames:
with open(f,’rb’) as fd:
shutil.copyfileobj(fd, wfd)
