Description vkyxurpmvfubjefphl 2021-07-23 10:43:06 UTC 
SUMMARY
At the time of writing and using current git version at the time of writing, copying and moving files completely ignores extended file attributes (such as user.xdg.tags, the ones Dolphin and the tags: kioslave utilize, or user.xdg.origin.url).
Sadly, I found out when I needed to find the xdg.origin.url of a file to be able to find a server used by a recently deceased colleague, and to my horror, having moved it using Krusader completely wiped out that url, that will never be found again.

STEPS TO REPRODUCE
1. Create tags with Dolphin, or set extended file attributes with setfattr.
2. Move or copy the file.
3. Resulting file will not preserve any of the extended file attributes.

OBSERVED RESULT
Tags or other metadata stored as xattr will not be copied, or "destroyed" when a file is moved.

EXPECTED RESULT
Files should retain that data.

SOFTWARE/OS VERSIONS
Windows: N/A
macOS: N/A
Linux/KDE Plasma: Ubuntu 21.04 (64b) Kernel 5.11.0.25-generic
(available in About System)
KDE Plasma Version: 5.22.3
KDE Frameworks Version: 5.84.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
While some can argue having information like download url or tags in files could be considered a security risk, it's trivial to wipe them out on demand, while it's impossible to restore them if they are lost by just copying or moving from Krusader.

Hello,

Thanks for reporting. Does the problem also happen copying files with Dolphin?

With Dolphin I added a "labelTest" tag to an "example.txt" file under Kubuntu 21.04, I used F5 in the git version of Krusader to copy that file to the same folder, and the resulting file "example2.txt" had the same attributes:

    $ getfattr -d example.txt
    # file: example.txt
    user.xdg.tags="labelTest"

    $ getfattr -d example2.txt 
    # file: example2.txt
    user.xdg.tags="labelTest"

Is that what you expected?

Note: 
- That didn't work under Kubuntu 20.04, maybe because [Please add Extended Attribute support (setxattr, getxattr)](https://bugs.kde.org/show_bug.cgi?id=116617) still was a problem there.

Using an updated Kubuntu 21.04, in About System I saw:
    Operating System: Kubuntu 21.04
    KDE Plasma Version: 5.21.4
    KDE Frameworks Version: 5.80.0
    Qt Version: 5.15.2
    Kernel Version: 5.11.0-25-generic
    OS Type: 64-bit
not the 
    KDE Plasma Version: 5.22.3
    KDE Frameworks Version: 5.84.0            
that you report. Do you have some special configuration?
