C drive in windows 10 shows full!

You may try run Disk Cleanup , it will scan your PC and show you temporary files where you could remove them.

Hi Mark_Konschak,

You can find folders which use many disk spaces on drive via powershell.

For example:

$targetfolder='C:\'
$dataColl = @()
gci -force $targetfolder -ErrorAction SilentlyContinue | ? { $_ -is [io.directoryinfo] } | % {
$len = 0
gci -recurse -force $_.fullname -ErrorAction SilentlyContinue | % { $len += $_.length }
$foldername = $_.fullname
$foldersize= '{0:N2}' -f ($len / 1Gb)
$dataObject = New-Object PSObject
Add-Member -inputObject $dataObject -memberType NoteProperty -name “foldername” -value $foldername
Add-Member -inputObject $dataObject -memberType NoteProperty -name “foldersizeGb” -value $foldersize
$dataColl += $dataObject
}
$dataColl | Out-GridView -Title “Size of subdirectories”

Hello Mark_Konschak,

If you recently or earlier upgraded to newer version from older version of Windows 10, you might want to remove files in Windows.old folder to gain more space on drive.

Regards.
