What is a way to sort a collection of file names based on their file extensions?

edit

One way to sort a collection of file names based on their file extensions is to use a programming language such as Python or Java to write a script that reads the file names in the collection, extracts the file extensions from each file name, and then sorts the file names based on their file extensions using a sorting algorithm such as merge sort or quicksort. Another way is to use a file manager or command-line interface that allows you to sort files based on their file extensions. For example, in Windows Explorer, you can sort files by clicking on the "Type" column header, which will group all files with the same file extension together.
