Deleting all files older than one hour in a folder

[Maxwell2006]

Hi,

I am new to PowerShell. What would be the proper command to delete all files
older than one hour within a specific folder?

Thank you,
Max

Something like this?

gci |? { [DateTime]::Now - $_.LastWriteTime -lt [TimeSpan]::FromHours(1) } | ri

The following should do what you want:

$now = get-date
get-childitem * |
where-object {$_.LastWriteTime -le $now.AddHours(-1)} |
remove-item -whatif

Once you are sure that the command does what you want repeat without
the -whatif parameter.

Nick,

I think your code removes the wrong files. It looks as if it deletes
files that are less than 1 hour old. The questioner wanted to remove
files more than one hour old.

As a general piece of advice, when using remove-item always test using
the -whatif parameter. PowerShell may protect you anyway. No point in
taking risk in my opinion.

Thank you very much Andrew for help.
This is exactly what I was looking for.

I am going to put this in a .ps1 run it every hour by using scheduled task
job. Would that be fine or I need some special configurations?

Thank you again,
Max

Remember that .ps1 files won't automatically run like vbscript files would.
You need to ensure your schduled task command looks something like this

C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe -Command
path_to_your_script.ps1

Doh! I must have misread the question. Or else I'm just careless.

Yeah, you should always tack on '-whatif' before you run something potentially hazardous.

<grin/> Don't worry about it. I've done it before and probably will do
it again. :(
