            Bug ID: 468505
           Summary: Get rid of VFS handles without affected found files
    Classification: Applications
           Product: krusader
           Version: 2.7.2
          Platform: Ubuntu
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: krusader-bugs-n...@kde.org

  Target Milestone: ---

SUMMARY
***
An easy way to get rid of VFS handles without deleting files shown in them is
necessary
***


STEPS TO REPRODUCE
1. Search for files meeting some search criteria,
2. Feed found results to a listbox (German: "In Dateifenster einspeisen")
3. There is no way to get rid of that listbox.

OBSERVED RESULT
p. 36 of the documentation warns: deleting a VFS results in deleting all files
shown in it.

EXPECTED RESULT
1. There should be a warning of how many files will be deleted if one confirms
it when deleting a VFS handle.
2. A means to get rid of VFS handles alone is necessary.



SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Xubuntu 20.04 LTS
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 5.68.0
Qt Version: Qt 5.12.8 (kompiliert gegen 5.12.8)

ADDITIONAL INFORMATION
After searching for files whose names meet certain criteria and which contain
e.g. a given keyword, I can click on a button "Feed to listbox". (Deutsch: In
Dateifenster einspeisen)

Then Krusader 2.7.2 asks me for a name for this search result list, a so called
virtual file system (VFS). By entering a name, I create such a VFS.

Then I can use the VFS like any other active directory, e.g. copy files from
there or move them to some other location or delete them (in fact, deleting the
result list really deletes the files from where they were found, which is very
dangerous since it differs from when one knows from Total commander and the
like)! So this might be considered a security issue, although described in the
documentation on page 36.

Krusader seems to memorize searches and search results in ~/.config/krusaderrc
and possibly also in ~/.local/share/krusader/virtualfilesystem.db.

Over time, therefore, more and more residues accumulate in these files. An easy
way to get rid of that without uninstalling Krusader and purging all its
associated files is important. 

In conjunction with VFS Krusader should not delete many files without asking a
security prompt where it indicates how many files it would delete besides the
VFS handle. There should be a means to just get rid of those VFS handles and
keeping the files which are shown in it.

(Unfortunately I was unable to compile Krusader 2.8.0 on my Xubuntu 20.04
system.)
