Powershell Move Files To Directory - Maintain Paths? - powershell

Question

Trying to make a simple backup script that will do as below:
Move the following
\source\example1.txt
\source\path\example2.txt
To
\dest\example1.txt
\dest\path\example2.txt
At the same time, renaming any files that already exist in dest.
My Code:
$src = "C:\Users\User\Desktop\test1"
$dest = "C:\Users\User\Desktop\test2"
Get-ChildItem -Path $src -Filter *.txt -Recurse | ForEach-Object {
$num=1
$nextName = Join-Path -Path $dest -ChildPath $_.name
while(Test-Path -Path $nextName)
{
$nextName = Join-Path $dest ($_.BaseName + " ($num)" + $_.Extension)
$num+=1
}
$_ | Move-Item -Destination $nextName
}
This almost works but it flattens all files into one folder in the dest.
(\source\path\example.txt becomes \dest\example.txt)
How to fix?

Answer 1

Following commented code snippet could do the job:
Get-ChildItem -Path $src -Filter *.txt -Recurse |
ForEach-Object {
$num=1
# ChildPath ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
$nextName = Join-Path -Path $dest -ChildPath $_.FullName.Replace("$src\", '')
# effective destination for current file
$destNew = $nextName | Split-Path
# create effective destination silently if necessary
if ( -not (Test-Path -Path $destNew) ) {
$null = New-Item $destNew -ItemType Directory
}
while(Test-Path -Path $nextName)
{
# ↓↓↓↓↓↓↓↓
$nextName = Join-Path $destNew ($_.BaseName + " ($num)" + $_.Extension)
$num+=1
}
$_ | Move-Item -Destination $nextName
}

Other method :
function Get-ItemNameWithNumberIfExist($NewPath, $BaseName, $Extension, $rang)
{
#build a new file name
if ($rang -eq 0)
{
$NewFileName="{0}{1}" -f $NewPath, $BaseName, $Extension
}
else
{
$NewFileName="{0}({1}){2}" -f $NewPath, $BaseName, $rang, $Extension
}
#build a new path file name (use combine for work on every SE)
$NewPathFile=[System.IO.Path]::Combine($NewPath, $NewFileName)
#recursive call if file exist
if (Test-Path -Path $NewPathFile)
{
$rang++
Get-ItemNameWithNumberIfExist $NewPath $BaseName $Extension $rang
}
else
{
$NewPathFile
}
}
$OldPath='C:\temp\tmp1\'
$NewPath='C:\temp\tmp2\'
Get-ChildItem $OldPath -file -Recurse | %{
$NewPath=$_.DirectoryName.Replace($OldPath, $NewPath)
#create directory without error if exist
New-Item -ItemType Directory -Path $NewPath -Force
#move item and rename if exist
move-item $_.FullName (Get-ItemNameWithNumberIfExist $NewPath $_.BaseName $_.Extension 0)
}
