file-utils: Use 'file-roller' in temp names
Currently File Roller uses .fr-XXXXXX
for temporary directory names
which if the directory isn't cleaned up after use (a known issue)
doesn't tell the user what program the directory was created by.
This changes it so that when File Roller needs a temporary directory
while creating or modifying an archive it uses .file-roller-XXXXXX
in
the target directory.
And when File Roller needs a temporary directory in ~/.cache
, ~
or
/tmp
to hold files opened directly from the archive it uses
~/.cache/file-roller/XXXXXX
, ~/file-roller/XXXXXX
or
/tmp/file-roller/XXXXXX
. So it groups the temporary directories under
a file-roller/
directory.
This way the user can understand better what the directories are from.
This is a follow up to the suggestion from @jfft in: #191 (comment 1717332)
