#cs
Description: Monitors the user defined directories for file activity.
Original: http://www.autoitscript.com/forum/index.php?showtopic=69044&hl=folderspy&st=0
Modified: Jack Chen
Syntax: _MonitorDirectory($Dirs = "", $Subtree = True, $TimerMs = 250, $Function = "_ReportChanges")
Parameters:
$Dirs - Optional: Zero-based array of valid directories to be monitored.
$Subtree - Optional: Subtrees will be monitored if $Subtree = True.
$TimerMs - Optional: Timer to register changes in milliseconds.
$Function - Optional: Function to launch when changes are registered. e.g. _ReportChanges
Syntax of your function must be e.g._ReportChanges($Action, $FilePath)
Possible actions: Created, Deleted, Modified, Rename-, Rename+, Unknown
Remarks: Call _MonitorDirectory() without parameters to stop monitoring all directories.
THIS SHOULD BE DONE BEFORE EXITING SCRIPT AT LEAST.
