It works for me.... I have just copied your custom file explorer string and when i open a folder it opens in new tab on already open lister
i guess i should add that i want to open folder shortcuts in new tabs (not only folders) seems like it works for me too with real folders (i never use that...)
for those interested i found a workaround using Akete plugin and Autohotkey
Akete setting :
[Akete]
lnk=C:\_common\programs\FARR Scripts\open_lnk.ahk
and in the open_lnk.ahk file :
shortcut = %1%
if InStr(shortcut, "C:\_user\Folder Shortcuts") {
FileGetShortcut, %shortcut%, OutTarget
Run, C:\Program Files\GPSoftware\Directory Opus\dopusrt.exe /cmd Go "%OutTarget%" NEWTAB
}
else {
Run, %1%
}
basically all .lnk files are "processed" by the open_lnk.ahk script (thanks to akete)
if the .lnk file is in my "folder shortcuts" folder, the target folder is extracted then passed to my "dopus command-line"
akete is a neat plugin
