Is it safe to install program files in a drive other than the default drive?

Our users asked:


They asked if install program files in a drive D is ir safe. In my case, my default drive where I usually install program files is drive C, but I was wondering if I could install the files in drive D. We think that there is no problem if you install software in drive D. No problem at all.

    Yes,, your other drives are more space on your pc, if you don’t use it, it just sets there empty. Just direct the file there.

    It is a common question because If you’re talking about the C:\Program Files folder, then yes you can safely move it somewhere else (e.g. to another drive). After you copy the folder, you’ll want to modify an entry in the Windows registry. Start up the registry editor by clicking Start -> Run and typing regedit. You’ll want to browse to the following location in the registry:
    HKEY_LOCAL_MACHINE\Software\Microsoft
    \Windows\CurrentVersion.

    Change the value of “ProgramFiles”, or “ProgramFilesDir” to the path of your folder. Just double-click on each of the above entries on the right side of the registry editor to change the path. If you copy the folder to the root of your D drive the path would be D:\Program Files.

    You also need to have a folder called Common Files inside of your Program Files folder. If it isn’t there, just create a new folder called Common Files.

    Go back to HKEY_LOCAL_MACHINE\Software\Microsoft\
    Windows\CurrentVersion and change the value of CommonFilesDir to the location of your Common Files folder.

    Please note that modifying the registry incorrectly can lead to problems.
