    Do I need the install.esd AND installx64.esd files on my disk?


    Hello everyone,

    I have both and install.esd and an installx64.esd file on my SSD, each occupy 2.7 GB on my SSD. I think I have them because I upgraded from win8 - correct me if I'm wrong.

    My question is that is it possible to save some disk space and remove those files? I do not plan to go back to win8 in the future.

    Thank you in advance!

    Suggestion :
    Why don't you copy them to an USB flash drive or to an external hard drive first, then delete them afterwards.
    You don't need them now, but they might come in handy in the future.
    That Install.esd is for your Windows 10. It can be used to convert into an ISO file which can then be burnt to a bootable installation DVD or USB. You can then use it to reinstall Windows 10 if you need to.

    Hi Adam, welcome to the Ten Forums.

    You can delete those files if you want to, although I would follow the David's suggestion in post above mine.

    If you decide to completely delete them, you might want to first create your own Windows 10 install media from them:

    Thank you very much David, I'll save them to my external drive :)

    You can check what version the files are for. If they are build 10240 and you are updated to build 10586, there isn't much point in keeping the old files. From an elevated ("run as administrator") command prompt type:

    DISM.exe /Get-WimInfo /WimFile:D:\install.esd /Index:1

    The part in red is the path to the esd file. Also you can try /Index:2 at the end to see if there is more than one Windows version in the esd file, but at 2.7 gb there probably isn't.

    Rename them.

    Reboot.

    Reboot again (why not)

    (If no problem) Delete them.
