My dataset consists of about 6000 txt files. Every three files have same initial name but diffrent last name.I want to write a code that first select all the three files has same initial name and then combine them in one file and delete them from directory at the same time. This process repeats onward. In the end I will left with 2000 files only.
For example, 123x.txt, 123y.txt, 123z.txt..... it be one group and so on. 123.txt
