    safe to delete AppData/Local?

    Is it safe to delete or change the location of AppData/Local and its
    subdirectories? I'm trying to regain space in C:

    Thanks

    No. That's where all your programs store their settings. Run the Disk
    Cleanup Wizard and delete all but last Restore Point if you are so short of
    space.

    Well, this is only partially true. The AppData\Local and
    AppData\LocalLow folders are the folders where applications store their
    "local machine only" settings. This means that these files are by
    default not synchronized to the roaming profile share (usually only in
    use for corporate users).
    The AppData\Roaming folder contains the settings for the applications
    (at least according to the guidelines). The AppData\Local folder should
    actually only contain volatile data or data which can be re-generated
    easily such as caches.

    In case you use roaming profiles you sign off at one machine then the
    AppData\Roaming tree is synchronized to the roaming profile share. When
    you log in on another machine your profile gets pulled from the roaming
    profile server. This by definition does not include the AppData\Local
    folder. Therefore on this machine this folder is basically empty.
    Windows will then create some default structures like Temp or Temporary
    Internet Files folders automatically (empty). Applications which do not
    respect the volatile nature of the AppData\Local folder do not respect
    the guidelines (I usually try to avoid using such programs).

    Therefore it is theoretically safe to remove all files from
    AppData\Local\*\** folders. However I am quite sure you cannot delete it
    entirely as Windows will complain that it needs it (at run time).

    In case the OP likes to free some space he should clean
    AppData\Local\Temp\* and look out for some large folders to clean up
    selectively. For example Outlook tends to write the mail archive folder
    there (AppData\Local\Microsoft\Outlook\Archive.pst. Just note that this
    is entirely correct from my point of view. This makes the Archive local.
    If I roam to another PC I don't need the archive. In case my HDD dies I
    just lose the archive (ie old e-mail). As the archive is usually growing
    quite fast it would be very bad to store it within the AppData\Roaming
    and synchronize it to the server at each login/logoff.

    br,

    Thanks for all the replies. I've decided to just buy a new HD. I
    backed up my entire PC. Problem is Windows Complete PC Restore can't
    even find the image DVD but that should be another thread. Thanks.
