Scan directories for large files

To scan directories for large files, you can use built-in tools available on your operating system. Here are methods for Windows, macOS, and Linux:

Linux / macOS (Terminal)

1. Find files larger than 100MB in a directory:

bash
CopyEdit
find /path/to/dir -type f -size +100M -exec ls -lh {} ; | awk '{ print $9 ": " $5 }'

2. List top 10 largest files recursively:

bash
CopyEdit
du -ah /path/to/dir | sort -rh | head -n 10

3. Only files, excluding directories:

bash
CopyEdit
find /path/to/dir -type f -exec du -h {} + | sort -rh | head -n 10

Windows (PowerShell)

1. List top 10 largest files in a folder:

powershell
CopyEdit
Get-ChildItem -Path "C:PathToDir" -Recurse -File | 
Sort-Object Length -Descending | 
Select-Object FullName, @{Name="SizeMB";Expression={[math]::round($_.Length / 1MB, 2)}} -First 10

2. Find all files larger than 100MB:

powershell
CopyEdit
Get-ChildItem -Path "C:PathToDir" -Recurse -File | 
Where-Object { $_.Length -gt 100MB } | 
Select-Object FullName, @{Name="SizeMB";Expression={[math]::round($_.Length / 1MB, 2)}}

Cross-platform Tools

sudo apt install ncdu      # Ubuntu/Debian
