I have a bunch of directories
C:\RI1
C:\RI2
C:\RI3
... C:\RI21
How can I check if they are all empty? I want to go further into the script only if one or more of them have files. If not, I want to exit. I tried this but it is searching for folder names and is giving me 21 as the answer
$directoryInfo = Get-ChildItem C:\RI* | Measure-Object
$directoryInfo.count
if ($directoryInfo.count -eq 0)
{
Write-host "Empty"
}
else
{
Write-host "Not Empty"
}
When you run Get-ChildItem C:\RI* you get all the child items in C:\ and filter the results with items which begin with "RI". You get the answer 21 since there are 21 folders in C:\ that starts with "RI".
I suggest that you run through all the folders using a foreach loop.
$folders = #("RI1", "RI2", "RI3")
foreach ($folder in $folders)
{
$path = "C:\$folder"
$directoryInfo = Get-ChildItem $path
if ($directoryInfo.count -eq 0)
{
Write-Host "Empty"
}
else
{
Write-Host "Not Empty"
}
}

I am creating a script that splits a target folder's files into subfolders of n length, where n is a number specified dynamically.
So basically, if Folder A has 9000 files, and I limit the number of files to 1000 per folder, the script would create nine sub-directories inside of Folder A with 1000 files each.
Here is working code:
param (
[Parameter(Mandatory,Position=0)]
[String]
$FileList,
[Parameter(Mandatory=$false,ValueFromPipelineByPropertyName)]
[Int32]
$NumFilesPerFolder = 1000,
[Parameter(Mandatory=$false,ValueFromPipelineByPropertyName)]
[Int32]
$FolderNumberPadding = 2
)
$Folders = Get-Content $FileList
Set-Location -LiteralPath ([IO.Path]::GetTempPath())
function Move-Files {
[CmdletBinding()]
param (
[Parameter(Mandatory,Position=0)]
[System.Collections.ArrayList]
$List,
[Parameter(Mandatory)]
[Int32]
$Index
)
$BaseFolder = [System.IO.Path]::GetDirectoryName($List[0])
$DestFolderName = $Index.ToString().PadLeft($FolderNumberPadding, '0')
$DestFolder = New-Item -Path (Join-Path $BaseFolder $DestFolderName) -Type Directory -Force
Move-Item $List -Destination $DestFolder -Force
}
foreach ($Folder in $Folders) {
$Files = Get-ChildItem -LiteralPath $Folder -File -Force
$filesidx = 1
$totalidx = $null
$groupidx = 0
$FilesToMove = [System.Collections.ArrayList]#()
foreach ($File in $Files) {
if($null -eq $totalidx){
$totalidx = $Files.Length
}
if($filesidx -eq 1){
$groupidx++
}
$FilesToMove.Add($File)
if($filesidx -eq $NumFilesPerFolder){
Move-Files -List $FilesToMove -Index $groupidx
$FilesToMove.Clear()
$filesidx = 1
}elseif($totalidx -eq 1){
Move-Files -List $FilesToMove -Index $groupidx
$FilesToMove.Clear()
break
}else{
$filesidx++
}
$totalidx--
}
}
Remove-Item $FileList -Force
$app = New-Object -ComObject Shell.Application
$appwin = $app.Windows()
foreach ($window in $appwin) {
if($window.Name -eq "File Explorer"){
$window.Refresh()
}
}
Invoke-VBMessageBox "Operation Complete" -Title "Operation Complete" -Icon Information -BoxType OKOnly
This code runs reasonably well, but it heavily bottlenecks when actually moving the files with Move-Item. I'd like to try and use RoboCopy here, but I am perplexed as to how I can implement it.
What I'm having trouble with is that the items I need to move are stored in a list (see the Move-Files function), and every item that needs to be moved are all in the same sub-directory. So I can't just do RoboCopy.exe C:\Source C:\Destination /mov.
How can I integrate RoboCopy here to accomplish my goal? I really need multi-threaded performance as this function will be responsible for moving thousands of files around in production on a frequent basis.
Any help would be greatly appreciated - please let me know if I can provide more information to further clarify my objective.
Thanks for any help at all!
My current script checks if a specific folder on some clients exists.
I'd like to check if the client is online or offline before checking if the folder exists.
My current script looks like this:
$CDS = Get-content C:\Users\XY\Desktop\Clientliste.txt
Foreach($c in $CDS) {
IF (Test-Connection -BufferSize 32 -Count 1 -ComputerName $c -Quiet) {
Foreach ($c in $CDS) {
$Test = Test-Path -path "\\$c\c$\apps\perl"
Start-Sleep -s 0.25
If ($Test -eq $True) {
Write-Host "Path exists on $c."
}
Else {
Write-Host "Path NOT exist on $c."
}
}
}
Else {
Write-Host "The remote computer " $c " is Offline"
}
}
I don't know how to link the foreach loops so that they work together.
Because when I run my script now, it goes after the first if request in the 2nd foreach loop and it does leave it first, when it finishes the 2nd foreach loop.
I don't want that. I want that if the client is online, it checks if the paths exists and then goes to the next client and checks again if it is online and then...
Maybe you can help me :)
Why do another identical loop over the items from the text file is you have already tested the machine is reachable?
Just remove that second loop and do:
$CDS = Get-Content -Path 'C:\Users\XY\Desktop\Clientliste.txt'
foreach($computer in $CDS) {
if (Test-Connection -BufferSize 32 -Count 1 -ComputerName $computer -Quiet) {
if (Test-Path -Path "\\$computer\C$\apps\perl" -PathType Container) {
Write-Host "Path exists on computer '$computer'."
}
else {
Write-Host "Path NOT exist on computer '$computer'."
}
}
else {
Write-Host "The remote computer '$computer' is Offline"
}
}
I frequently have to copy a single file to multiple destinations, so i'm trying to write a script to make that go faster. it seems to work fine when i'm dealing with local files, but fails without any errors when running on a file that is on a mapped network drive.
at first I was using copy-item, and I couldn't make that work, so i used robocopy. that does the trick, but if the file already exists, i have an if statement using test-path which is supposed to skip to a user input that asks if you want to overwrite.. this is not working. i should say the one that checks the folder exists is working, but the one that checks for the file name always comes back true. for now, i have it just forcing an overwrite with robocopy because most of the time that's what i'll want to do anyway.
here's what i have right now.. "K:" is the mapped network drive i'm copying to, and i'm usually copying files from another mapped network drive "T:". I also should mention i have this set up to run from the context menu in windows (7) explorer, and it passes the file path to the script via %L and $args.
any advice is appreciated. (i apologize in advance, i know it's rather rough.. This is somewhat new to me.)

I'm stuck. I have a PowerShell script which looks to a specific folder for files which are older than 30 days from the last modified date (additionally, it'll create the folder if it doesn't exist). It creates the folder, it gives me the total files, it'll list all of the files in a test query, but it won't actually count the number of 30+ day old files. I've tried several methods to get this count (some deriving from other solutions to delete old files from this site), but PowerShell just doesn't want to do it.
Here's my code so far...
$HomePath = $env:USERPROFILE
$CompanyFolder = "\Company"
$TimeSensativeFolder = "\TimeSensative"
$TimeSensativePath = $HomePath+$CompanyFolder+$TimeSensativeFolder
$OldFilesAmount = 0
$TotalFilesAmount = 0
$TimeLimit = (Get-Date).AddDays(-30)
$StatusOK = "No old files were found in the time sensative folder."
$StatusCreated = "The time sensative folder was created."
$StatusError1 = "There were old files found in the time sensative folder!"
$StatusError2 = "Unable to create the time sensative folder!"
function MakeTimeSensativeFolder ($TimeSensativePath) {
try {
md $TimeSensativePath -Force -ErrorAction Stop
Write-Host $StatusCreated
}
catch {
Write-Host $StatusError2
}
}
function CountOldFiles () {
$OldFilesAmount = $OldFilesAmount + 1
}
if(!(Test-Path $TimeSensativePath -PathType Container)) {
MakePHIFolder $TimeSensativePath
}
else {
}
try {
$TotalFilesAmount = (Get-ChildItem $PHIPath -Recurse -File | Measure-Object).Count
# I've tried this...
Get-Item $PHIPath | Foreach {$_.LastWriteTime} -ErrorAction Stop
if (Get-Content $_.LastWriteTime | Where-Object {$_ -gt $TimeLimit}) {
CountOldFiles
}
# And I've tried this...
Get-ChildItem -Path $PHIPath -Recurse -File | Foreach-Object {
if (Get-Content $_.LastWriteTime | Where-Object {$_ -gt $TimeLimit}) {
CountOldFiles
}
}
# I've even tried this...
Get-ChildItem $PHIPath -Recurse -File | ? {
-not $_.PSIsContainer -and $_.LastWriteTime -lt $TimeLimit
} | CountOldFiles
# And this, as well...
Get-ChildItem -Path $PHIPath -Recurse -File | Where-Object {$_.LastWriteTime -gt $TimeLimit} | CountOldFiles
}
catch {
MakeTimeSensativeFolder $TimeSensativePath
}
# Used for testing.
<#
Get-ChildItem $TimeSensativePath -Recurse -File
Write-Host "TimeSensative folder exists:" $TimeSensativePathExists
Write-Host "Home TimeSensative path:" $TimeSensativePath
Write-Host "Old files found:" $OldFilesAmount
Write-Host "Total files found:" $TotalFilesAmount
Exit
#>
# Determining proper grammar for status message based on old file count.
if ($OldFilesAmount -eq 1) {
$StatusError1 = "There was "+$OldFilesAmount+" old file of "+$TotalFilesAmount+" total found in the PHI folder!"
}
if ($OldFilesAmount -gt 1) {
$StatusError1 = "There were "+$OldFilesAmount+" old files of "+$TotalFilesAmount+" total found in the PHI folder!"
}
# Give statuses.
if ($OldFilesAmount -gt 0) {
Write-Host $StatusError1
}
else {
Write-Host $StatusOK
}
Depending on which I tried, I would get no result or I'd get something like this:
Get-Content : Cannot find drive. A drive with the name '12/22/2016 17' does not exist.
At C:\Users\nobody\Scripts\PS1\ts_file_age.ps1:54 char:14
+ if (Get-Content $_.LastWriteTime | Where-Object {$_ -gt $Tim ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (12/22/2016 17:String) [Get-Content], DriveNotFoundException
+ FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetContentCommand
In any instance, there's no old file count as I'm endeavoring to demand.
It's been a bit of a head scratcher. Any advice?
Thanks so much in advance!
Filtering files with last write time is easy enough. Like so,
$allFiles = gci
$d = (Get-Date).adddays(-30)
$newFiles = #()
$oldFiles = #()
$allFiles | % { if ($_.lastwritetime -ge $d) { $newFiles +=$_ } else { $oldFiles += $_ } }
What's done here is that first all the files are set in a collection. This isn't mandatory, but one can browse the collection to check that it's been populated properly. This is useful in cases one has complex paths or exclusion filters.
The second step is just to get a DateTime that is used later to divide files into old and new ones. Just like the sample did, so nothing interesting here. Actually, there's one little thing. The date is -30 days, but hours, minutes and seconds are based on current time. So if there's really tight limit, consider using midnight time ([datetime]::Today).AddDays(-30)
The third step is to declare two empty collections for new and old files.
The last step is to iterate through the $allFiles and check the last write time. If it's greater or equal to the cutpoint, add it into $newFiles, othervise $OldFiles.
After the last step, further processing should be simple enough.
This is what I do to get (delete in this case) files older than X days:
$Days = 5
$limit = (Get-Date).AddDays(-$Days)
$CurrentDate = Get-Date
#This will delete all files older than 5 days
Get-ChildItem -Path $Workdir -Recurse -Force | Where-Object { !$_.PSIsContainer -and $_.LastWriteTime -lt $limit } | Remove-Item -Force
I would like to copy files between folders. Just modified (CSV files with new entries) in current day and one day before.
Here is my code:
foreach ($file in (Get-ChildItem "D:\Shares\WinCAP Data\DAYPROT\OFS-222_2")) {
if ($file.LastWriteTime = (Get-Date).AddDays(-1)) {
Copy-Item -Path "D:\Shares\WinCAP Data\DAYPROT\OFS-222_2\*.csv" -Destination "\\Oracle\MP"
"copying $file"
} else {
"not copying $file"
}
}
What is wrong - any suggestions?
You need to compare the date with -gt otherwise your're looking for files that were copied at that EXACT time.
Note that doing (Get-Date).AddDays(-1) is perfectly valid but will give you anything modified in the last 24 hours.
$DestinationFolder = "\\Oracle\MP\"
$EarliestModifiedTime = (Get-date).AddDays(-1)
$Files = Get-ChildItem "D:\Shares\WinCAP Data\DAYPROT\OFS-222_2\*.csv"
foreach ($File in $Files) {
if ($File.LastWriteTime -gt $EarliestModifiedTime)
{
Copy-Item $File -Destination $DestinationFolder
Write-Host "Copying $File"
}
else
{
Write-Host "Not copying $File"
}
}
If you didn't want to write out the "Copying ..." and "Not Copying ..." then you could simplify this quite a bit.
$DestingationFolder = "\\Oracle\MP\"
$EarliestModifiedTime = (Get-date).AddDays(-1)
Get-ChildItem -File |? { $_.LastWriteTime -gt $EarliestModifiedTime } | Copy-Item -Destination $DestingationFolder
Finally, if you want to copy anything since the beginning of (eg midnight at the start of) yesterday then change the following line:
$EarliestModifiedTime = (Get-date).AddDays(-1).Date
#Mr Tree I have one more related question.
I got few times per day new file at the location D:\Shares\WinCAP Data\DAYPROT\OFS-HT (location 1) with fixed name abcDD.MM.YYYY.csv (abc03.09.2015.csv) and I have a service which every 10 minutes call my powershell script below. I made as you suggest before in upper posts. My goal is: 1. to check if there is new file with name abcDD.MM.YYYY.csv | 2. rename it into abcDD.MM.YYYYHT.csv and move it to "\Oracle\MP\PURO\" (location 2) folder where I need to rewrite it with existing for current day.
Problem is that if the file already exists on the location 2, script does not want to move it and rewrite it? Thanks for hints.
$DestingationFolder = "\\Oracle\MP\PURO\"
$EarliestModifiedTime = (Get-date).AddDays(-1)
Get-ChildItem "D:\Shares\WinCAP Data\DAYPROT\OFS-HT\*.csv" | ?{!($_.fullname -match "HT\.csv")} | Rename-Item -NewName { $_.Name -replace "\.csv", "HT.csv" }
$Files = Get-ChildItem "D:\Shares\WinCAP Data\DAYPROT\OFS-HT\*.csv" -File
foreach ($File in $Files) {
if ($File.LastWriteTime -gt $EarliestModifiedTime)
{
Move-Item $File -Destination $DestingationFolder
Write-Host "Moving $File"
}
else
{
Write-Host "Not moving $File"
}
}
