In PowerShell 2 0  it is still not possible to get the Copy-Item cmdlet to create the destination folder  you ll need code like this    destinationFolder    C  My Stuff Subdir   if    Test-Path -path  destinationFolder    New-Item  destinationFolder -Type Directory  Copy-Item    server1 Upgrade exe  -Destination  destinationFolder   If you use -Recurse in the Copy-Item it will create all the subfolders of the source structure in the destination but it won t create the actual destination folder  even with -Force

Yes  add the -Force parameter     copy-item  from  to -Recurse -Force

I have stumbled here twice  and this last time was a unique situation and even though I ditch using copy-item I wanted to post the solution I used    Had a list of nothing but files with the full path and in majority of the case the files have no extensions  the -Recurse -Force option would not work for me so I ditched copy-item function and fell back to something like below using xcopy as I still wanted to keep it a one liner  Initially I tied with Robocopy but it is apparently looking for a file extension and since many of mine had no extension it considered it a directory    filelist      C  Somepath test location here file   C  Somepath test location here2 file2     filelist       echo f   xcopy          Replace  somepath    somepath NEW        Hope it helps someone

Here s an example that worked for me   I had a list of about 500 specific files in a text file  contained in about 100 different folders  that I was supposed to copy over to a backup location in case those files were needed later   The text file contained full path and file name  one per line   In my case  I wanted to strip off the Drive letter and first sub-folder name from each file name   I wanted to copy all these files to a similar folder structure under another root destination folder I specified   I hope other users find this helpful     Copy list of files  full path   file name  in a txt file to a new destination  creating folder structure for each file before copy  rootDestFolder    F  DestinationFolderName   sourceFiles   Get-Content C  temp filelist txt foreach  sourceFile in  sourceFiles        filesplit    sourceFile split           splitcount    filesplit count       This example strips the drive letter  amp  first folder   ex  E  Subfolder    but appends the rest of the path to the rootDestFolder      destFile    rootDestFolder              sourceFile split      2   splitcount   -join            Output List of source and dest      Write-Host        Write-Host      sourceFile     -ForegroundColor Green     Write-Host      destFile           Create path and file  if they do not already exist      destPath   Split-Path  destFile     If   Test-Path  destPath     New-Item  destPath -Type Directory       If   Test-Path  destFile     Copy-Item  sourceFile  destFile

My favorite is to use the  Net  IO DirectoryInfo  class  which takes care of some of the logic   I actually use this for a lot of similar scripting challenges   It has a  Create   method that creates directories that don t exist  without errors if they do   Since this is still a two step problem  I use the foreach alias to keep it simple   For single files    IO DirectoryInfo  to        create    cp  from       As far as your multi file directory match  I would use RoboCopy over xcopy   Remove the     from your from and just use   RoboCopy exe  from  to     You can still add the  r  Recurse    e  Recurse including Empty   and there are 50 other useful switches   Edit  Looking back at this it is terse  but not very readable if you are not using the code often   Usually I have it split into two  like so     IO DirectoryInfo  to  Create   cp  from  to   Also  DirectoryInfo is the type of the Parent property of FileInfo  so if your  to is a file  you can use them together     IO FileInfo  to  Parent Create   cp  from  to
