How do I find the 10 largest files in a directory structure?

Try this script

Get-ChildItem -re -in * |
  ?{ -not $_.PSIsContainer } |
  sort Length -descending |
  select -first 10

Breakdown:

The filter block "?{ -not $_.PSIsContainer }" is meant to filter out directories. The sort command will sort all of the remaining entries by size in descending order. The select clause will only allow the first 10 through so it will be the largest 10.

See Which Folders Are Taking Up Space in Windows 8.1 Settings, How do I find the largest files in a folder? Find Large Files in Windows 10 Without Third-Party Tools Previously, I wrote how to find the largest file and directory in Linux . Today, I would like to offer you a solution for Windows.

This can be simplified a bit because Directories have no length:

gci . -r | sort Length -desc | select fullname -f 10

How To Find The Size Of A Directory In Linux, How do I find the largest files in a directory in Linux? There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. du command : Estimate file space usage. sort command : Sort lines of text files or given input data. head command : Output the first part of files i.e. to display first 10 largest file. find command : Search file.

I've blogged about a similar problem where I want to find the largest files in a directory AND all subdirectories (the entire C: drive for example), as well as list their size in a nice easy to understand format (GB, MB, and KB). Here's the PowerShell function I use that lists all files sorted by size in a nice Out-GridView:

Get-ChildItem -Path 'C:\SomeFolder' -Recurse -Force -File 
        | Select-Object -Property FullName
             ,@{Name='SizeGB';Expression={$_.Length / 1GB}}
             ,@{Name='SizeMB';Expression={$_.Length / 1MB}}
             ,@{Name='SizeKB';Expression={$_.Length / 1KB}} 
        | Sort-Object { $_.SizeKB } -Descending 
        | Out-GridView

Outputting to the GridView is nice because it allows you to easily filter the results and scroll through them. This is the faster PowerShell v3 version, but the blog post also shows a slower PowerShell v2 compatible version.

And of course if you only want the top 10 largest files, you could just add a -First 10 parameter to the Select-Object call.

How To Find Largest Top 10 Files and Directories On Linux / UNIX , How do I find out what files are taking up space? This works, but only gives me the largest files in that directory [in my example the /cep directory]. I'm also looking for the largest files within each of the subdirectories of that directory. For example, I want the 10 largest files of some directory and the 10 largest files of each subdirectory under that directory.

If you care about a bit of formatting of the result-set, here are two functions with nicer-looking outputs:

#Function to get the largest N files on a specific computer's drive
Function Get-LargestFilesOnDrive
{
Param([String]$ComputerName = $env:COMPUTERNAME,[Char]$Drive = 'C', [Int]$Top = 10)
Get-ChildItem -Path \\$ComputerName\$Drive$ -Recurse | Select-Object Name, @{Label='SizeMB'; Expression={"{0:N0}" -f ($_.Length/1MB)}} , DirectoryName,  Length | Sort-Object Length -Descending  | Select-Object Name, DirectoryName, SizeMB -First $Top | Format-Table -AutoSize -Wrap    
}

#Function to get the largest N files on a specific UNC path and its sub-paths
Function Get-LargestFilesOnPath
{
    Param([String]$Path = '.\', [Int]$Top = 10)
    Get-ChildItem -Path $Path -Recurse | Select-Object Name, @{Label='SizeMB'; Expression={"{0:N0}" -f ($_.Length/1MB)}} , DirectoryName,  Length | Sort-Object Length -Descending  | Select-Object Name, DirectoryName, SizeMB -First $Top | Format-Table -AutoSize -Wrap
}

How do I find the 10 largest files in a directory structure, in your Music, Documents, Downloads, and other folders, including the Recycle Bin. It's not nearly as detailed as something like WinDirStat, but great for a quick peek at your home folder. To find the largest files in a particular location, just include the path besides the find command: Find Top File Size in Specific Location The above command will display the largest file from /home/tecmint/Downloads directory. That’s all for now.

Here is the fastest way to get this done I am aware of:

$folder  = "$env:windir" # forder to be scanned
$minSize = 1MB

$stopwatch =  [diagnostics.stopwatch]::StartNew()

$ErrorActionPreference = "silentlyContinue"
$list = New-Object 'Collections.ArrayList'
$files = &robocopy /l "$folder" /s \\localhost\C$\nul /bytes /njh /njs /np /nc /fp /ndl /min:$minSize
foreach($file in $files) {
    $data = $file.split("`t")
    $null = $list.add([tuple]::create([uint64]$data[3], $data[4]))
}

$list.sort() # sort by size ascending
$result = $list.GetRange($list.count-10,10) 
$result | select item2, item1 | sort item1 -Descending

$stopwatch.Stop()
$t = $stopwatch.Elapsed.TotalSeconds
"done in $t sec."

  • That's great ---- I figured out how to format the final result using format-table but what I"m not clear on is the syntax ?{ } and the $_ I'm guessing these are shortforms for some statement construct?
  • The ?{} syntax is short for where-object which is a filter expression. Essentially powershell will pass every object to the ?{} clause in the from of $_. If the return is $true, then the object will continue down the pipeline, otherwise it will be filtered out.
  • this is memory intensive command and propotional to the size of content being searched I guess.
  • Plus the '.' isn't even required. Could simplify that front part to just "gci -r | ..." since the default path is the current dir.
  • Seems that it doesn't answer original question.
  • This doesn't answer the question which is asking about listing files in Powershell. There's no "head" command available. It would apply nicely to bash, but that's not the topic of this question.
