Using Get-childitem to get a list of files modified in the last 3 days

Question

Code as it is at the moment  get-childitem c  pstbak     -include   pst   Where-Object      LastWriteTime -lt  get-date  AddDays -3       Essentially what I am trying to do is get a list of all PST files in the folder above based on  them being newer than 3 days old  I d then like to count the results  The above code doesn t error but brings back zero results  there are definitely PST files in the folder that are newer than three days  Anyone have any idea

Try this    Get-ChildItem -Path c  pstbak     -Filter   pst            LastWriteTime -gt  Get-Date  AddDays -3      Count

Here s a minor update to the solution provided by Dave Sexton  Many times you need multiple filters  The Filter parameter can only take a single string whereas the -Include parameter can take a string array  if you have a large file tree it also makes sense to only get the date to compare with once  not for each file  Here s my updated version    compareDate    Get-Date  AddDays -3        Get-ChildItem -Path c  pstbak     -Filter    pst     mdb  -Recurse   Where-Object      LastWriteTime -gt  compareDate   Count

Very similar to previous responses  but the is from the current directory  looks at any file and only for ones that are 4 days old   This is what I needed for my research and the above answers were all very helpful   Thanks   Get-ChildItem -Path   -Recurse        LastWriteTime -gt  Get-Date  AddDays -4

I wanted to just add this as a comment to the previous answer  but I can t  I tried Dave Sexton s answer but had problems if the count was 1   This forces an array even if one object is returned     System Object    gci c  pstback  -Filter   pst               LastWriteTime -gt  Get-Date  AddDays -3     Count   It still doesn t return zero if empty  but testing  -lt 1  works
