Finding modified date of a file folder

Question

I am very new to PowerShell  and I was hoping I could get some help creating a script that tells me the modified date of a file   I wish I knew more about PowerShell  as I feel like I am asking a lot  all my free-time this week will be dedicated to learning PowerShell better   Pointing me in the direction of where to learn how to do this would be very helpful as well   Here is the complete rundown  I need to run a report daily that checks a list of computers at 90 different stores to make sure their a certain backup was performed  The modified date should tell if the backup had been performed  and will be set to the previous date   If the modified date is yesterday  then there does not need to be an output  If it is not yesterday  I would like to have the output in the PowerShell window  or to a text file  whichever would be easier   I also have to check that a folder is no older than seven days for each of the 90 stores  with the same criteria for the output  The idea that I have would be like this for each store  For Store 1   Check file date for   server store computer c  folder  newest modified date in folder  if date equals yesterday    then do nothing if date does not equal yesterday    then output  Test did not backup   check folder modified date for   server sample store backupfolder if date equals  lt 7 days old    then do nothign if date equals  gt 7 days old    then output  test did not backup    Sorry for not proving my research effort  I am very new to Powershell and I was on a deadline to get this done   I have  since yesterday  learned how to do everything that I needed to do with this script   Thanks to  Keith for setting me on the correct path   I ended up using the following code to accomplish my goal of only out-putting the location where result was false    a   Get-ChildItem   server XXX Received Orders       Where    LastWriteTime -ge  Get-Date  AddDays -7   if   a    Get-ChildItem   server XXX Received Orders       Where    LastWriteTime -ge  Get-Date  AddDays -7         Else        STORE XXX HAS NOT RECEIVED ANY ORDERS IN THE PAST 7 DAYS       b   Get-ChildItem   COMP NAME Folder       Where    LastWriteTime -ge  Get-Date  AddDays -1   if   b    Get-ChildItem   COMP NAME TFolder       Where    LastWriteTime -ge  Get-Date  AddDays -1         Else        STORE XXX DID NOT RUN ITS BACKUP LAST NIGHT

If you run the Get-Item or Get-ChildItem commands these will output System.IO.FileInfo and System.IO.DirectoryInfo objects that contain this information e.g.:

Get-Item c:\folder | Format-List

Or you can access the property directly like so:

Get-Item c:\folder | Foreach {$_.LastWriteTime}

To start to filter folders & files based on last write time you can do this:

Get-ChildItem c:\folder | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)}
