A lot of years ago, circa Exchange 2010, there was a limitation on pipelines-within-pipelines which had to be worked around. Files already include name, size, dates, so select all of those and add a calculated property of the file hash using Get-FileHash (MD5 and SHA options): gci | select *, @{L='Hash'; E={ ($_ | Get-FileHash).Hash }} Get-ChildItem | Select-Object -Property FullName, CreationTime, Length, @{Label='Hash'; Expression={ ($_ | get-filehash).Hash}} but even then you could do what you want with a traditional loop and no pipeline: $results = foreach ($file in get-childitem) { # a hashtable of things you want to be # in each object ('row') of the output: $data = @{ Name = $file.Name SizeGB = $file.Length / 1GB Hash = ($file | Get-FileHash).Hash } [pscustomobject]$data }
