The code below simply opens the owning folder, it does not select the passed item, as I suspected:
[code] Dim f As FolderItem
f = GetFolderItem(“Network Interfaces.app”) // Beside the running project
showurl f.parent.urlpath[/code]
Or use NSWorkspaceMBS.selectFile(file as folderitem) as boolean in MBS Plugin for Mac:
[code]dim f as FolderItem
f=SpecialFolder.Desktop.Child(“test.txt”)
if NSWorkspaceMBS.selectFile(f) then
MsgBox “Ok”
else
MsgBox “failed”
end if[/code]
for Windows, you can use WindowsShellExecuteMBS:
[code]dim e as Integer
dim f as FolderItem
// show documents folder
f = SpecialFolder.Documents
e = WindowsShellExecuteMBS(0, “explore”, f.AbsolutePath, “”, “”, 10)[/code]
I prefer my Mac
Dim f As FolderItem
f= SpecialFolder.Pictures // or other folder
If f <> Nil Then
f.Launch
End If

but it does not highlight the file as requested by the op. 
Here’s the SHOpenFolderAndSelectItems version, tested in 32 and 64. It will allow you to pop open a Windows Explorer with multiple files selected.

in that code what is COM.SIZEOF_PTR ?
When i try to compile I get “this Item does not exist”
Thanks

Its used to space things correctly for 32/64 bit, its a value that changes from 4 to 8 depending on if you’re compiling for 32 or 64 bit (the size of a pointer, which changes), you can use a const inside a #If Target32Bit if its not in that edition of xojo:
At the top of that method put:
#If Target32Bit
Const SIZEOF_PTR = 4
#Else
Const SIZEOF_PTR = 8
#EndIf
Then remove the COM. infront of the two lines which have COM.SIZEOF_PTR so it uses the const instead.
Out of interest, which version of Xojo are you trying this on as if the #if doesn’t work on that edition, just replace it with a 4 or 8 depending on your target.

Thanks!
I’m not sure… On my mac when I tried to complier for Windows in was either 2018r3 0r 2019R1.1… When I tried in parallels with Windows 7 it was some older version… maybe from 2015 or 2016… I can tell you this evening after I get home what version it was.
