Find All Documents Created or Modified by a Particular User in Specific Date Time

Requirement is to find all documents which are uploaded to the SharePoint environment during the past one Month. PowerShell can do the reporting well. Lets see the code:

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

# Set the date Filter
$dateFilter = (Get-Date).AddMonths(-1) #Past Month
"File, Created Time, File Size" | out-file NewDocuments.csv

# Get all Webs
$webs = Get-SPWebApplication "http://sharepoint.crescent.com" | Get-SPSite -Limit All | Get-SPWeb -Limit All

#Iterate through webs
ForEach ($web in $webs) 
{
   #Iterate through All Lists
    ForEach ($list in $web.Lists) 
 {
  #Check for Document Libraries  
        If ($list.BaseType -eq "DocumentLibrary") 
  {
     #Iterate through All documents
                   ForEach ($item in $list.Items)
   {
                  If ($item.URL.StartsWith("_")) {Break} #Skip _catalogs, etc
                  If ($item.URL.EndsWith(".aspx")) {Break} #Skip Form pages
                    If ($item.File.TimeCreated -ge $dateFilter) 
    {
                      $result = """$($web.URL)/$($item.URL)"", $($item.File.TimeCreated), $( [Math]::Round($item.File.Length/1024,2))"
                      $result | Out-File NewDocuments.csv -Append
                 }
                }
        }
    }
}

Same way, we can find all documents uploaded to SharePoint sites based on Date criteria by just checking $item.File.TimeLastModified property. Say For instance,

• You may be interested to see all old documents created an year back 
• All documents which are not changed during the past one year.

Find All Documents Created or Modified by a Particular User:
In an another situation, the request is to find all documents either created by  modified by a particular user in SharePoint 2007.

  $WebApps = @()

                        If ( ($item.File.Author -like "*domain\user*") -or ($item.File.ModifiedBy -like "*domain\user*"))

                             $result = "$($item.File.Name) `t $($item.File.Author) `t $($item.File.ModifiedBy) `t $($item.File.TimeCreated) `t $($item.File.TimeLastModified) `t  $( [Math]::Round($item.File.Length/1024,2)) `t $($web.URL)/$($item.URL)"
                              $result | Out-File AllDocsByUser.csv -Append
                           }
                     }
                }
           }
      }
