browse folder function problem

[boskap]

hello
Sorry my english is not so good

i have a question / problem with the browse folder function
when i choose a folder and set a variable with this folder , adding a subfolder the path is ok

$Back_Rec_Path = $folderbrowserdialog2.SelectedPath
$global:DestPath = $Back_Rec_Path + "\BACKUP\" + $Env:USERNAME # zb.: C:\Backup\Username...

the $destpath variabe is then ok, like d:\test\backup\

but when i choose a root drive like d:\ the $destpath is d:\\backup
now i have to backslash

what i make wrong

The following is a safe way to join multiple path segments.

$global:DestPath = [system.io.path]::Combine($Back_Rec_Path.'BACKUP',$Env:USERNAME)

$global:DestPath = [system.io.path]::Combine($Back_Rec_Path.'BACKUP',$Env:USERNAME)
