I decided to create this component, because the Windows 
ShellChangeNotifier isn't able to return for what and where something 
happend !<br>
So with this component, you can track a file or a dir (and sub dirs), and 
it returns for each file what happend : new file, file deleted or file 
changed.<br>
<br>
<b>Properties :</b>
<br><br>
<b>FileToSpy</b> The filename to spy, if you run this component in 
smFile mode<br>
<b>PathToSpy</b> The parent dir to spy, if you run this component in 
smPath mode.<br>
<b>ExcludeSubPaths</b> Sub-path from the root path (in smPath 
mode) excluded of the spy mode<br>
<b>WatchSubTree</b> if TRUE, then the subtrees of the parent dir 
are spied too (can consume processor time !)<br>
<b>RefreshFrequency</b> milliseconds between which the 
component decide to finally call you (15000 (15 secs) is a good 
value)<br>
<b>SpyMode</b> smNone : inactive, smFile : spy only the 
"FileToSpy", smPath : spy the Dir (and subdirs if checked)<br>
<b>ShowDebug</b> returns debug information too (using neOther 
Status)<br>
<b>CallOnceByGroup</b> make only a call (for a specific event), even 
if there were more than one file touched (used to say something like 
"they are new file(s) in dir" when files were added)<br>
<b>OnNotifyChange</b> New notify function. It returns, for each file, 
its size, its attributes and the reason (File Changed, New File or File 
Deleted. neOther is a debug string)
