    I suppose that you could follow the initial copy with an rsync.

    two things:

    1. if you encounter this bug (i have not) and do not report it then you
    are missing a GREAT opportunity to throw more light (and interest) onto
    the problem..

    it works like this: if one person files a bug and no one in the universe
    posts something like: "Me too, using CentOS 14.9, KDE4.8.3, EXT4 on a
    RAID 12 array over VPN to a rack mount cloud on SLED 11 in NYC....but,
    it works great on my local USB"

    well, if there is only one who reports with sufficient *facts* for the
    developers to begin to track down the ability to DUPLICATE the bug it
    will _never_ get fixed (maybe)..

    so, if you have seen this bug it is your _duty_ to add your encounter
    and important info to the existing bug report!!!

    2. use rsync...with just a itty-bitty little script (you can click) you
    can do all the backup/refresh/retrieve/sync you want without dragging
    and dropping anything, or wondering if empty folders have been moved or
    or or or

    and, you can set that up to be done while you sleep (via cron)..

    The bug was reported for dolphin 11.0, 11.1, 11.2 and finally was reported that it was a KDE problem and reported fixed for KDE 4.4.0 but was re-submitted as a bug this time affecting more than KDE. Somebody reported in Ubuntu that there is an unwillingness to do anything about it since it only affects a few who choose to do high volume of file copying. Last I heard, the resolve was to only do such transfers using the CLI and to always copy rather than to move files. Leaves me with a bad taste frankly. We have a great stable filesystem and powerful OS and someones asleep at the wheel working on the basics of simple disk read/write algorithms that have been used for over 55 years!

    my 'advice' stands:

    1. those affected should bug report it until the cows come
    home..(including in 12.1, 15.3 and later!!)

    2. while waiting for 'someone' to wake up, those with the problem should:

    a. use something known to work (rsync is only one)

    b. search until finding the bug(s) in the code and provide a patch

    c. if finding the bug is beyond the ability of those with the problem,
    then study programming faster/harder/in more depth.

    and i add:

    giving up or just *****in' in _these_ fora ain't helping!
    (the KDE code developers are _.-=* N O T *=-._ here)

    do not forget, in free and open software, *we* are included in that
    'someone' who is asleep (or just *****in') at the wheel!

    un-fricking-believable. I recently moved to KDE and just got hit by this bug in Kubuntu 11.10, almost 2 years since this post was first started! It boggles my mind that a bug this CRITICAL can exist that long in KDE. Is the Q/A of KDE that bad? Do they do any testing at all? This is serious business folks, we are talking DATA LOSS here. People should be screaming about this bug from the roof tops as if it was a major security flaw.

    https://bugs.kde.org/show_bug.cgi?id=162211

    This bug has been standing, it seems, since 2008. Unreal! I love the comments on that bug report about how it's a "kernel issue" or "mac os, windows have the same problem." I call BS. I've NEVER experienced losing files like this before EVER... and this is even REPEATABLE. It happens every time with KDE. Also, just do a search about "dolphin file loss" and you'll see plenty of results.

    So long KDE! if I have to worry about LOSING DATA by doing something as mundane as copying directory, then KDE is worthless to me.

    Unfortunately, the session is still out as they have been able to repeat the problem in certain kernels, certain desktops (KDE,Gnome), but yet not in CLI. So those who do the development/testing are each blaming each other. Here in this forum, there are those who know of the problem but lack the skills to do proper reporting to bugzilla, those who have their own work-arounds, those who have the skills to try and fix but lack either the time or structure to send a fix upstream, and those who have sent an upstream fix but it was kicked out due to the fix breaking something even more important. I lost almost lost 1000's of files in Gnome, did loose many 1000's in kde (thank god I always use a back-up protocol). Yes I would like it fixed too.

    You lost a thousand files in gnome, using dolphin as the title says? Or
    using something else?

    Me, I have not seen this problem. But I very rarely use GUI for large
    copy/move jobs, I use rsync or mc.


    In any case, it is important that *every one* of you with this problem
    pester the devs with bugzillas.

    While the title says dolphin, I have found GUI based file loss is prevalent in varying degrees under a multitude of filemangers. Dolphin by far exhibits the most noticable and easiest one to reproduce.

    As some of the more experienced users here have already stated, it is important to keep adding your bug reports to the relevant bugzillas until these issues are squashed. For those that have requirement s to move and copy large numbers of files, it is far more robust to use rsync, and for those that like graphical environments to do this, consider using grsync (for Gnome), or krsync (for KDE users).

    Yes, I don't know why this hasnt received top priority. It does seem to be a tricky one but it's certainly not imaginary. And I, for one, HAVE seen it happen via the command line. Anyway, I gave up and went back to Gnome and Fedora 15. A drastic way to solve a problem, but I've had no trouble since. Bummer, though, as I greatly prefer KDE.
