"switch" custom command not working properly

i've made a custom command .. accessed by CTRL + SHIFT + O

/window
/switch
site undupe %f

i am in FXP mode
and currently the LEFT PANE is activated

file1 is highlighted in the LEFT PANE
file2 is highlighted in the RIGHT PANE
file3 is highlighted in the RIGHT PANE
file4 is highlighted in the RIGHT PANE

when issue my custom command this is the result
[L] [CMD] /window
[L] [CMD] /switch
[R] site undupe file2
[R] 200- Unduped: file2
[R] 200-
[R] 200- 1 dupes deleted.
[R] 200 Command Successful.
[R] site undupe file3
[R] 200 Command Successful.
[R] site undupe file3
[R] 200 Command Successful.
[R] site undupe file4
[R] 200- Unduped: file4
[R] 200-
[R] 200 Command Successful.

BUT i wanted file1 unduped

if NO files are highlighted in the Right Pane
the result is
[L] [CMD] /window
[L] [CMD] /switch

FlashFXP v5 b3801
Windows XP pro

BUT i wanted file1 unduped

Did you want file1 unduped on left or right side?

If the left side then omitting the /switch should provide the result you're looking for.

Yes i wanted file1 unduped on the right side

You'll need to do something like this

This will work in FlashFXP v5.0.0.3801 and up.

{
/set @f@ %f
/switch
site undupe @f@
/switch
}

The code above works by grouping the commands on each selected item.

/set @f@ %f
Will set the variable @f@ to %f which is the current item in the active browser (.i.e. left side).
/switch
Switches to the opposite side (i.e. right side)
site undupe @f@
Sends the command to the right side.
/switch
Switches back to the original side (.i.e. left side)

This command block is then repeated for each selected item.

I noticed that the /window command doesn't work properly when used with the /switch command, only commands that are sent to the active window are logged. I am changing this behavior in the next build to include commands from both sides when /switch is used.

I selected files named 1,2,3,4,5 and the result in the status window looks like this.

[L] [CMD] /set @f@ 1
[L] [CMD] /switch
[R] site undupe 1
[R] 200 Command Successful.
[R] [CMD] /switch
[L] [CMD] /set @f@ 2
[L] [CMD] /switch
[R] site undupe 2
[R] 200 Command Successful.
[R] [CMD] /switch
[L] [CMD] /set @f@ 3
[L] [CMD] /switch
[R] site undupe 3
[R] 200 Command Successful.
[R] [CMD] /switch
[L] [CMD] /set @f@ 4
[L] [CMD] /switch
[R] site undupe 4
[R] 200 Command Successful.
[R] [CMD] /switch
[L] [CMD] /set @f@ 5
[L] [CMD] /switch
[R] site undupe 5
[R] 200 Command Successful.
[R] [CMD] /switch

works beautifully ... thank you
