Rename duplicated names in a tab separated text file?

[Recce]

How to rename duplicated names in a single tab separated text file using AutoIt?

Is this possible at all?

The problem is that the name column must be no longer then 12 letters/numbers and at the same time no duplicated names is accepted.

I added a sample tab separated text file if needed.

Check first for files so use FileFindFirstFile then FileFindNextFile and write all files in text file or ini and when some names match then rename one

How is this possibly in a single tab separated text file?

I am very new to AutoIt and no programmer but is "FileFindFirstFile" not for finding files only?
