I am trying to copy all files in folders and sub-folders not older than 300 minutes, but the code I got working only copies the files in the main folder, it doesn't copy the files in subfolders. At the destination I don't want to maintain the folder structure of the original files, I just want to put all the origin files into a single specific destination folder. This is the code I have:
Powershell -NoL -NoP -C "&{$ts=New-TimeSpan -M 300;"^
"Get-ChildItem "C:\Origin" -Filter '*.dat'|?{"^
"$_.LastWriteTime -gt ((Get-Date)-$ts)}|"^
%%{Copy-Item $_.FullName 'C:\Destination'}}"
Could someone help me out please? Thanks in advance.
Here's a modified script for you you can save as "Copy-Unique.ps1" you can run from a batch file.
function Copy-Unique {
# Copies files to a destination. If a file with the same name already exists in the destination,
# the function will create a unique filename by appending '(x)' after the name, but before the extension.
# The 'x' is a numeric sequence value.
[CmdletBinding(SupportsShouldProcess)] # add support for -WhatIf switch
Param(
[Parameter(Mandatory = $true, ValueFromPipeline = $true, Position = 0)]
[Alias("Path")]
[ValidateScript({Test-Path -Path $_ -PathType Container})]
[string]$SourceFolder,
[Parameter(Mandatory = $true, Position = 1)]
[string]$DestinationFolder,
[Parameter(Mandatory = $false)]
[int]$NewerThanMinutes = -1,
[Parameter(Mandatory = $false)]
[string]$Filter = '*',
[switch]$Recurse
)
# create the destination path if it does not exist
if (!(Test-Path -Path $DestinationFolder -PathType Container)) {
Write-Verbose "Creating folder '$DestinationFolder'"
$null = New-Item -Path $DestinationFolder -ItemType 'Directory' -Force
}
# get a list of file FullNames in this source folder
$sourceFiles = @(Get-ChildItem -Path $SourceFolder -Filter $Filter -File -Recurse:$Recurse)
# if you want only files not older than x minutes, apply an extra filter
if ($NewerThanMinutes -gt 0) {
$sourceFiles = @($sourceFiles | Where-Object { $_.LastWriteTime -gt (Get-Date).AddMinutes(-$NewerThanMinutes) })
}
foreach ($file in $sourceFiles) {
# get an array of all filenames (names only) of the files with a similar name already present in the destination folder
$destFiles = @((Get-ChildItem $DestinationFolder -File -Filter "$($file.BaseName)*$($file.Extension)").Name)
# for PowerShell version < 3.0 use this
# $destFiles = @(Get-ChildItem $DestinationFolder -Filter "$baseName*$extension" | Where-Object { !($_.PSIsContainer) } | Select-Object -ExpandProperty Name)
# construct the new filename
$newName = $file.Name
$count = 1
while ($destFiles -contains $newName) {
$newName = "{0}({1}){2}" -f $file.BaseName, $count++, $file.Extension
}
# use Join-Path to create a FullName for the file
$newFile = Join-Path -Path $DestinationFolder -ChildPath $newName
Write-Verbose "Copying '$($file.FullName)' as '$newFile'"
$file | Copy-Item -Destination $newFile -Force
}
}
# you can change the folder paths, file pattern to filter etc. here
$destFolder = Join-Path -Path 'C:\Destination' -ChildPath ('{0:yyyy-MM-dd_HH-mm}' -f (Get-Date))
Copy-Unique -SourceFolder "C:\Origin" -DestinationFolder $destFolder -Filter '*.dat' -Recurse -NewerThanMinutes 300
Changed the code to now take a datetime
object to compare against rather than an amount of minutes. This perhaps makes the code easier to understand, but certainly more flexible.
function Copy-Unique {
# Copies files to a destination. If a file with the same name already exists in the destination,
# the function will create a unique filename by appending '(x)' after the name, but before the extension.
# The 'x' is a numeric sequence value.
[CmdletBinding(SupportsShouldProcess)] # add support for -WhatIf switch
Param(
[Parameter(Mandatory = $true, ValueFromPipeline = $true, Position = 0)]
[Alias("Path")]
[ValidateScript({Test-Path -Path $_ -PathType Container})]
[string]$SourceFolder,
[Parameter(Mandatory = $true, Position = 1)]
[string]$DestinationFolder,
[string]$Filter = '*',
[datetime]$NewerThan = [datetime]::MinValue,
[switch]$Recurse
)
# create the destination path if it does not exist
if (!(Test-Path -Path $DestinationFolder -PathType Container)) {
Write-Verbose "Creating folder '$DestinationFolder'"
$null = New-Item -Path $DestinationFolder -ItemType 'Directory' -Force
}
# get a list of file FullNames in this source folder
$sourceFiles = @(Get-ChildItem -Path $SourceFolder -Filter $Filter -File -Recurse:$Recurse)
# if you want only files newer than a certain date, apply an extra filter
if ($NewerThan -gt [datetime]::MinValue) {
$sourceFiles = @($sourceFiles | Where-Object { $_.LastWriteTime -gt $NewerThan })
}
foreach ($file in $sourceFiles) {
# get an array of all filenames (names only) of the files with a similar name already present in the destination folder
$destFiles = @((Get-ChildItem $DestinationFolder -File -Filter "$($file.BaseName)*$($file.Extension)").Name)
# for PowerShell version < 3.0 use this
# $destFiles = @(Get-ChildItem $DestinationFolder -Filter "$baseName*$extension" | Where-Object { !($_.PSIsContainer) } | Select-Object -ExpandProperty Name)
# construct the new filename
$newName = $file.Name
$count = 1
while ($destFiles -contains $newName) {
$newName = "{0}({1}){2}" -f $file.BaseName, $count++, $file.Extension
}
# use Join-Path to create a FullName for the file
$newFile = Join-Path -Path $DestinationFolder -ChildPath $newName
Write-Verbose "Copying '$($file.FullName)' as '$newFile'"
$file | Copy-Item -Destination $newFile -Force
}
}
# you can change the folder paths, file pattern to filter etc. here
$destFolder = Join-Path -Path 'D:\Destination' -ChildPath ('{0:yyyy-MM-dd_HH-mm}' -f (Get-Date))
Copy-Unique -SourceFolder "C:\Origin" -DestinationFolder $destFolder -Filter '*.dat' -Recurse -NewerThan (Get-Date).AddMinutes(-300)
When you have saved the above code to let's say 'C:\Scripts\Copy-Unique.ps1' you can then call it from a batch file like:
Powershell.exe -NoLogo -NoProfile -File "C:\Scripts\Copy-Unique.ps1"
