    What is the lib folder?


    Hi,
    I just noticed a folder called "lib" in Program Files (x86).
    Is this folder a win 10 thing? What does it do?
    Thanks,
    Ed

    I don't have a 'Program Files (x86)\Lib' folder on any of my Win10 PCs, so not a standard part of Win 10 by the looks of it.

    What files (if any) does it contain? Their properties may have a manufacturer's name on the Details tab. If there are no files, the creation date of the Lib folder may give a clue. What else in the Program Files (x86) folder has the same creation date?

    Thanks for the quick response. I found a txt file that mentions Oracle.
    The lib folder contains about 10 sub folders and about 2 dozen files, mostly .jar files, whatever that is.

    This...

    A JAR (Java ARchive) is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution.

    Perhaps it was a program you installed.

    Did you install Java runtime environment? Perhaps for one of your browsers? That comes from Oracle.

    OK, I found a Java 8 update 101 with the same date.
    I don't recall that I had installed that. What is it good for?
    Can I uninstall it?

    Some software may require it, Minecraft is one.
