    Default Javaw.exe - I have four files on my computer. Do I need them all?

    While installing the Eclipse IDE it asks where the javaw.exe file is. I dont know what that means - I'm brand new to all this stuff. So I Windows Explorer > Search > This PC and among the drives I get four results. So it appears I have four files on my computer named javaw.exe. So I'm assuming that I dont need all four of these files, and in fact, only need one.

    Like I said, I'm new. I assume, like with many program installs, there's a file-foundation that needs to exist and that javaw.exe is in brick in that foundation. Perhaps it's a file needed to run java? I assume this cause it's attached to other downloads since I now have four copies of it. I've never been asked by an install program to find javaw.exe, so I didnt know this may be an issue. But I imagine that it's not a good thing to have multiples of the same file - that I should probably keep just one copy, keep it updated, and point everything to the one "javaw.exe" file.

    Say I'm right - where would the best place be to keep javaw.exe? My User folder?

    Your thoughts? And I off-base, on-base?

    Thank you.

    The javaw.exe file is part of an installed package. There would be one for each JRE and two for each JDK you have installed.
    You should not change the contents of any of the installed packages at this time.

    Do you know what java packages have been installed on your PC?
    I don't use the Eclipse IDE for java so I can not help you with its setup.
    If you don't understand my answer, don't ignore it, ask a question.
