function Get-FolderSize { <# .SYNOPSIS Get-FolderSize Returns the size of folders in MB and GB. You can change the base path, omit folders, as well as output results in various formats. .DESCRIPTION This function will get the folder size in MB and GB of folders found in the basePath parameter. The BasePath parameter defaults to the current directory. .PARAMETER BasePath This parameter allows you to specify the base path you'd like to get the child folders of. It defaults to where the module was run from via (Get-Location). .PARAMETER FolderName This parameter allows you to specify the name of a specific folder you'd like to get the size of. .PARAMETER AddTotal This parameter adds a total count at the end of the array .PARAMETER OmitFolders This parameter allows you to omit folder(s) (array of string) from being included .PARAMETER Output Use this option to output the results. Valid options are csv, xml, or json .PARAMETER OutputPath Specify the path you want to use when outputting the results as a csv, xml, or json file Do not include a trailing slash Example: C:\users\you\Desktop Defaults to (Get-Location) This will be where you called the module from .PARAMETER OutputFile This allows you to specify the path and file name you'd like for output Example: C:\users\you\desktop\output.csv .PARAMETER AddFileTotals This parameter allows you to add file totals to the results Note: This will reduce performance of the script by around 30%! .EXAMPLE Get-FolderSize | Format-Table -AutoSize FolderName Size(Bytes) Size(MB) Size(GB) $GetCurrent 193768 0.18 MB 0.00 GB $RECYCLE.BIN 20649823 19.69 MB 0.02 GB $SysReset 53267392 50.80 MB 0.05 GB Config.Msi 0.00 MB 0.00 GB Documents and Settings 0.00 MB 0.00 GB Games 48522184491 46,274.36 MB 45.19 GB .EXAMPLE Get-FolderSize -BasePath 'C:\Program Files' FolderName Size(Bytes) Size(MB) Size(GB) 7-Zip 4588532 4.38 MB 0.00 GB Adobe 3567833029 3,402.55 MB 3.32 GB Application Verifier 353569 0.34 MB 0.00 GB Bonjour 615066 0.59 MB 0.00 GB Common Files 489183608 466.52 MB 0.46 GB .EXAMPLE Get-FolderSize -BasePath 'C:\Program Files' -FolderName IIS FolderName Size(Bytes) Size(MB) Size(GB) IIS 5480411 5.23 MB 0.01 GB .EXAMPLE $getFolderSize = Get-FolderSize $getFolderSize | Format-Table -AutoSize FolderName Size(GB) Size(MB) Public 0.00 GB 0.00 MB thegn 2.39 GB 2,442.99 MB .EXAMPLE $getFolderSize = Get-FolderSize -Output csv -OutputPath ~\Desktop $getFolderSize FolderName Size(GB) Size(MB) Public 0.00 GB 0.00 MB thegn 2.39 GB 2,442.99 MB (Results will also be exported as a CSV to your Desktop folder) .EXAMPLE Sort by size descending $getFolderSize = Get-FolderSize | Sort-Object 'Size(Bytes)' -Descending $getFolderSize FolderName Size(Bytes) Size(MB) Size(GB) Users 76280394429 72,746.65 MB 71.04 GB Games 48522184491 46,274.36 MB 45.19 GB Program Files (x86) 27752593691 26,466.94 MB 25.85 GB Windows 25351747445 24,177.31 MB 23.61 GB .EXAMPLE Omit folder(s) from being included Get-FolderSize.ps1 -OmitFolders 'C:\Temp','C:\Windows' .EXAMPLE Add file counts for each folder Note: This will slow down the execution of the script by around 30% $results = Get-FolderSize -AddFileTotal PS /Users/ninja/Documents/repos/PSFolderSize> $results[0] | Format-List * FolderName : .git Size(Bytes) : 228591 Size(MB) : 0.22 Size(GB) : 0.00 FullPath : /Users/ninja/Documents/repos/PSFolderSize/.git HostName : njambp.local FileCount : 382 #> [cmdletbinding( DefaultParameterSetName = 'default' )] param( [Parameter( Mandatory = $false, Position = 0, ParameterSetName = 'default' )] [Alias('Path')] [String[]] $BasePath = (Get-Location), [Parameter( Mandatory = $false, ParameterSetName = 'default' )] [Alias('Name')] [String[]] $FolderName = 'all', [Parameter( ParameterSetName = 'default' )] [String[]] $OmitFolders, [Parameter( ParameterSetName = 'default' )] [Switch] $AddTotal, [Parameter( ParameterSetName = 'default' )] [Switch] $AddFileTotals, [Parameter( ParameterSetName = 'default' )] [Switch] $UseRobo, [Parameter( ParameterSetName = 'default' )] [Parameter( ParameterSetName = 'outputWithType' )] [ValidateSet('csv','xml','json')] [String] $Output, [Parameter( ParameterSetName = 'default' )] [Parameter( ParameterSetName = 'outputWithType' )] [String] $OutputPath = (Get-Location), [Parameter( ParameterSetName = 'default' )] [String] $OutputFile = [string]::Empty ) begin { #Get a list of all the directories in the base path we're looking for. $allFolders = Get-FolderList -FolderName $FolderName -OmitFolders $OmitFolders -BasePath $BasePath #Create array to store folder objects found with size info.
