Exporting Results of Script to CSV - powershell

Question

I've been searching for a script that simply lists folders in a share and their size. I found the following but I'm getting hung up on how to export the output I'm seeing to an easy to read CSV. It amazes me how something so simple has turned into something difficult. Suggestions welcome!
$colItems = Get-ChildItem "C:\Users\user.name\Desktop" | Where-Object {$_.PSIsContainer -eq $true} | Sort-Object
foreach ($i in $colItems)
{
$subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
$i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}

Answer 1

Based on your script:
## C:\Users\UserName\Desktop\Test\SO_50359947.ps1
$colItems = Get-ChildItem "$($Env:USERPROFILE)\Desktop" |
Where-Object {$_.PSIsContainer} | Sort-Object
$data = ForEach ($i in $colItems){
$subFolderItems = Get-ChildItem $i.FullName -recurse -force -ea 0|
Where-Object {!$_.PSIsContainer} |
Measure-Object -Property Length -sum | Select-Object Sum
[PSCustomObject]#{
Folder = $i.FullName
Size = "{0,10:N2} MB" -f ($subFolderItems.sum / 1MB)
}
}
$data
#$data | Export-Csv "$($Env:USERPROFILE)\Desktop\your.csv" -NoType
Sample output (on a different tree)
> $data
Folder Size
------ ----
Q:\test\2018\03 0,37 MB
Q:\test\2018\04 0,83 MB
Q:\test\2018\05 383,57 MB
Uncomment the last line to write to a csv file.

Here is one way using custom objects:
Get-ChildItem "$home\Desktop" -Directory |
ForEach-Object {
$contents = Get-ChildItem -Path $_.FullName -Recurse
[PsCustomObject]#{
FolderName = $_.Name
SizeMB = [Math]::Round(($contents | Where-Object PsIsContainer -eq $false | Measure-Object -property Length -Sum).Sum / 1MB,2)
SubFolders = ($contents | Where-Object PsIsContainer -eq $true | Measure-Object).Count
Files = ($contents | Where-Object PsIsContainer -eq $false | Measure-Object).Count
}
}
This gives output like this:
FolderName SizeMB SubFolders Files
---------- ------ ---------- -----
Folder1 438.38 19 124
Folder2 34925.72 306 3779
To send this to CSV, simply append the following after the last bracket:
| Export-Csv "$home\Desktop\Folders.csv" -NoTypeInformation

Answer 3

There's a couple ways to do this, but I think the least confusing would be to simply add that information to the item using Add-Member. Then output the desired data via Export-Csv.
$colItems = Get-ChildItem "C:\Users\user.name\Desktop" |
Where-Object {$_.PSIsContainer -eq $true} |
Sort-Object |
%{ Add-Member -InputObject $_ -NotePropertyName 'FolderSize' -NotePropertyValue (Get-ChildItem $_.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object -ExpandProperty Sum) -PassThru}
$colItems | Select FullName,FolderSize | Export-Csv -NoType

Answer 4

Please assign to some variable after getting all the file details from the desktop/any location and create the excel
$subFolderItems = Get-ChildItem "$home\Desktop" -Directory |
ForEach-Object {
$contents = Get-ChildItem -Path $_.FullName -Recurse
[PsCustomObject]#{
FolderName = $_.Name
SizeMB = [Math]::Round(($contents | Where-Object PsIsContainer -eq $false | Measure-Object -property Length -Sum).Sum / 1MB,2)
SubFolders = ($contents | Where-Object PsIsContainer -eq $true | Measure-Object).Count
Files = ($contents | Where-Object PsIsContainer -eq $false | Measure-Object).Count
}
}
$subFolderItems | out-file C:\Users\thiyagu.a.selvaraj\Desktop\PowerShell\FileSizeOutput.xls

Answer 5

In my opinion, using CSV for your use case isn't the best plan because (in my folder) there are files that are over 1000 MB, so csv will break up some file sizes. To make a tab delimited file, which can just as easily be parsed by most systems, simply modify your scripts output string.
I changed the -- to a tab character, and added an output at the end of the line
"{0}`t{1:N2} MB" -f $i.fullname,($subFolderItems.sum / 1MB) >> output.csv
The final script is below; you will probably need to change output.csv to your prefered output file location.
$colItems = Get-ChildItem "C:\Users\user.name\Desktop" | Where-Object {$_.PSIsContainer -eq $true} | Sort-Object
foreach ($i in $colItems)
{
$subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
"{0}`t{1:N2} MB" -f $i.fullname,($subFolderItems.sum / 1MB) >> output.csv
}

If you don't insist on using pure powershell, on Windows 10 (sufficiently new) you can just call bash:
bash -c "du -h | sed 's/\s\+/,/'"
To show how it affects the resulting csv, a longer example:
bash -c "du -m | sed 's/\([0-9]\+\)\s\+\(.*\)/\1MB,\2/'"
