The following should give you a start.
Basically I'm looping through each report in the "AllReports" collection and calling the OutputTo method to save a copy to a specified path.

VB Code:
  1. Private Sub Export_Reports()
  2. Dim rptTemp As AccessObject
  3. Dim sPath As String
  4.  
  5.     sPath = "C:\Reports\"
  6.        
  7.     DoCmd.SetWarnings False
  8.    
  9.     For Each rptTemp In Application.CurrentProject.AllReports
  10.         DoCmd.OutputTo ObjectType:=acOutputReport, _
  11.                         ObjectName:=rptTemp.Name, _
  12.                         OutputFormat:=acFormatRTF, _
  13.                         OutputFile:=sPath & rptTemp.Name
  14.     Next rptTemp
  15.    
  16.     DoCmd.SetWarnings True
  17. End Sub
