Question

Most Windows computers have a Common Files folder inside of Program Files. What is its purpose?

Answer 1

• Common Files Folder What's it for?
• Special Folders and Custom Folders

That said, I feel that folder exists mostly because MS wanted a place for its own libs shared among many programs - although it doesn't seem to get used by MS very much either!
In practice, few applications use it.

Maybe it is a requirement for an application desiring to obtain a "Designed for XP/Vista/nnn" logo(?) that it should use that folder to store files that are common within the application (this is speculation on my part - so don't take my word for it!).

Answer 2

• The Folder "Common Files" holds Common Folders and files of different softwares.

• These files are shared files so that other softwares/programs can use these files and its functions.

• Majority of the programs put their common files under one folder called "Common Files"
