RO????.bac & RO????.tmp.LOG Files ?! ...

Archived from groups: microsoft.public.windowsxp.basics (More info?)

Where ???? is a 4 digit hexadecimal number, I've discovered hundreds
of these file pairs in my C:\Windows\System32 on each of my networked
systems running Windows XP Home. All the RO????.tmp.LOG files are 0
bytes and the corresponding RO????.bac vary in size up to about 20 mB.
Does anyone know what these are? I took a copy of all burned to CD
then deleted them and everything seems to work OK ....

    Stephen,

    I'm working with another user in a different group right now with the same
    problem. If we find what they are I'll let you know

    I suspect that they might have something to do with System Restore.

    After deleting them, I went into System Restore and nearly all the
    restore points were gone ...

    Stephen,

    The other user stated the file date and times do not correspond to system
    restore points, so at this point it's not known if SR has anything to do
    with them. Also stated his system was bought new on 5/4/2004 and these files
    were dated back to 8/31/2003.

    All the best,

    Only a majority of my Restore points were deleted; one or two still
    remained.

    I think these files might contain a kind of supplementary information,
    perhaps when some element(s) of the system undergo a particularly
    drastic change, and might not be needed for some routine "minor"
    Restore points.

    What would constitute a 'minor' restore point?

    Another point. These files are easily deleted (unlike critical System
    stuff), although there is some evidence of some backup character (2
    corresponding files for each 4 digit hexadecimal designation).

    The SR deletion must be coincidental unless some malware is coming into play
    here. The System Restore file store is located under "System Volume
    Information."

    Perhaps a routine "System Check Point" and no software installations
    or deletions? Maybe certain Windows updates?

    System Restore only does one kind of restore point. There are no other undo
    points saved.

    Mighty strong coincidence ! Same action on both my systems BTW.

    Just last week I was considering using the System Restore and had an
    abundance of points to choose from. After the deletions, only 2.

    OK, if the files are not related to System Restore, then WHAT ARE
    they?

    Keep in mind that all the file names start with RO (Restore
    O(something)?) ...

    I don't know what they are, I have no such corresponding file on either of
    my two networked systems, not in the location you specified or anywhere
    else. Further, the deletion of "tmp" files should have no effect on any
    function on your computer.

    You might want to make sure you antivirus is up to date and run a virus
    scan. Also, you should probably check for any malware on your systems. I
    would suggest you download, install and run Ad Aware.

    I don't know what those files are nor should they have any effect on System
    Restore.

    Thanks Mike; good advice, and done all that stuff as SOP.

    BTW, using NAV 2004, Norton Personanal Firewall 2005, and Spyware
    Doctor. I suppose that any of these might be storing info in those
    files.

    However, deleting them definitely removed potential System Restore
    points ....

    Well, I honestly don't know what those files are or what might be creating
    them.

    You might check the event viewer to see if the files correspond to some
    issue that might be regularly coming up on your system; note, it could be
    some background issues so you might not even be aware. Open Control Panel,
    open Administrative Tools, open Event Viewer and look for errors in the
    various sections. When you find one, double click, the information
    contained within might give a clue as to what's going on.

    Also, have you checked the properties of those time files, right click,
    select properties, there may be information in the properties that might
    give a clue as to the source of those files.

    Stephen,

    What name brand system do you have and when did you purchase it?
    I'm asking because I want to see if yours and the other poster has the same
    machine.

    2 Systems, both Dell -

    P-4 , about 2 1/2 years
    Celeron , about 5 months

    BTW - over the past 48 hours or so since I deleted the files from both
    systems, lots of varied use, but NO new ones have appeared;
    go figure ...

    Stephen,

    From the other poster....

    Quote:
    I figured out what the files are!
    These files are a result of using Registry Compressor (version 2.0) from
    Rose City Software. Every time the program is run, it creates registry
    backup files that can be used to restore the registry. I have deleted these
    files and all is well. The System32 folder which contained 2GB is now down
    to less than 500MB.
