Delete OLD files

[markstaylor]

I am trying to compare the date of a list of files (each file) to the current date. If it's older than 60 day's I want to delet it. I can't figure out how to compare the dates. I can get the CreationDateISO but it has the time, and the File.Attributes Date is different. I'm comfused

2 years too late... but

function File.Age( cFile )
	local nNow = String.Replace(System.GetDate(DATE_FMT_ISO), "-", "", false);
  local cDate = String.Replace(File.GetAttributes(cFile).CreationDateISO,"-","",false);
  local nT = String.Find(cDate, "t", 1, false)
	local nFile = String.ToNumber(  String.Left(cDate,nT-1) )

  return Math.Abs(nNow-nFile)
end

Silly me -- this really isn't right at all!
This doesn't take into account that days only go to 30 and months only to 12.... Late night yesterday... disregard that function....

Here's a version that will probably work for most... You can take it from here to be more specific to each month's days.

function File.AgeInDays( cFile )
  -- This uses averages of:
  -- 365.25 days per year
  -- 30.44 days per month (365.24 days per year/12 months)
  -- Becuase of this; it's not 100% accurate.
  
  local cNow = String.Replace(System.GetDate(DATE_FMT_ISO), "-", "", false);
  local cDate = String.Replace(File.GetAttributes(cFile).WriteDateISO,"-","",false);
  local nT = String.Find(cDate, "t", 1, false)
  local cFile =  String.Left(cDate,nT-1)

  local nFileY = String.Left(cFile,4)
  local nFileM = String.Mid(cFile,5,2)
  local nFileD = String.Right(cFile,2)

  local nNowY = String.Left(cNow,4)
  local nNowM = String.Mid(cNow,5,2)
  local nNowD = String.Right(cNow,2)

  local nFileDays = Math.Ceil( (nFileY*365.25) + (nFileM * 30.44) + nFileD )
  local nNowDays = Math.Ceil( (nNowY*365.25) + (nNowM * 30.44) + nNowD )

  return Math.Abs( nNowDays - nFileDays )
end
