I'm not sure what these are or what I should (or should not) do with them--please advise.

F7536EF0D78A77B889EEBE98BF96BA5321A1FDE0.heu

F7536EF0D78A77B889EEBE98BF96BA5321A1FDE0.heu where: /

1C04C61346A1FA3139A37D860ED92632AA13DECF.heu where:/Users/me/Documents/TRASH ITEMS6:29:2011

1C04C61346A1FA3139A37D860ED92632AA13DECF.swz where:/Users/me/Documents/TRASH ITEMS6:29:2011

1C04C61346A1FA3139A37D860ED92632AA13DECF.swz where: /

 

 

These show in "macintosh HD"

    They certainly aren't OSX system files so you can probably trash them.

    A little google searching on ".swz extension" and ".heu extension" implies they are associated with adobe flash.  Possibly cache and temporary files.

     

    Were are you seeing these?  What did you do to get those listings in your first post?  Files listed as "file://localhost/..." is not the standard notation and I really don't understand the context of the first group in that listing.

    When I click on macintosh HD in Finder I get these 4:

    file://localhost/1C04C61346A1FA3139A37D860ED92632AA13DECF.heu

    file://localhost/1C04C61346A1FA3139A37D860ED92632AA13DECF.swz

    file://localhost/F7536EF0D78A77B889EEBE98BF96BA5321A1FDE0.heu

    file://localhost/F7536EF0D78A77B889EEBE98BF96BA5321A1FDE0.swz

     

    And that's what I don't understand.  Unless you rename it I believe "macintosh HD" is the root of your boot volume.  You should be seeing things like Applications, Library, etc. as icons or as a list of names.  And those names won't look like "file://localhost/...".  While I realize it's the url notation for a file on your machine (localhost) I don't understand why you are seeing that.  At the very least filenames in the finder can never have a visible ':' in them.

     

    At any rate we're going down a rat hole.  Just get rid of them.

    I just got a new Mac Mini and I used the Migration Assistant to merge everything in from my Time Machine disk. Afterwards, I noticed there are a bunch of these files scattered all over the place.

     

    The .heu files all seem to be 151 bytes long, while the .swz files vary in size.

     

    I'm wondering if I can just delete them all without harming anything.

     

    EDIT: I went ahead and deleted some, and each time I'm presented with a password dialog.  These are apparently admin-type files that cannot be deleted without an admin login.

     

    EDIT2: on second thought, when I set up the new machine, I used the same name and username as the other one.  When I tried to run the Migration Assistant, it refused to merge the older files owned by this user into the new machine because for whatever reason it must think you are no longer yourself -- the new machine means you're someone else!

     

    So I went into the new machine and changed my name and username.  Then the MA moved all of my previous files and settings from the old machine's Time Machine backup to the new machine.  Then I deleted the new / renamed user on the new machine and continued to use the name I've been using forever -- the "old me" as it were.
