Answer 1

I am looking for a program that can find the longest line of a .txt file. It should run on Microsoft Windows.

I've listed two FREE solutions below that may suffice for your need.

Method 1

You could use: wc -L "c:\folder\file.txt" from the CoreUtils for Windows for example if you just need the number of the length of the longest line in that file. This would be a freebie too by the way.

Method 2

You can do this in Windows with PowerShell as well for a particular file:

1. Get the maximum length number of a record in a file:

   GC "c:\folder\file.txt" | Measure -Property length -Maximum | Select Maximum

2. Get the content of the longest line/record in a file

   GC "c:\folder\file.txt" | Sort -Property length | Select -last 1
