RealTimeSync: Some questions

[kevinffs]

I have a FFS batch job that syncs multiple subdirectories off the root folder:

<FolderPairs>
<Pair>
<Left>C:\RootFolder</Left>
<Right>\\ServerName\RootFolder</Right>
</Pair>

<GlobalFilter>
<Include>
<Item>\SubFolderA\*</Item>
<Item>\SubFolderC\*</Item>
<Item>\SubFolderE\*</Item>
</Include>

I have RTS monitoring the root folders.

Problem is if something changes in the root folder or other subdirectory then RTS fires off the FFS job.

I am wondering whether I should configure RTS to monitor all the required subdirectories rather than the root folders, thus:

<FreeFileSync XmlType="REAL">
<Directories>
<Item>C:\RootFolder\SubFolderA</Item>
<Item>C:\RootFolder\SubFolderC</Item>
<Item>C:\RootFolder\SubFolderE</Item>
<Item>\\ServerName\RootFolder\SubFolderA</Item>
<Item>\\ServerName\RootFolder\SubFolderC</Item>
<Item>\\ServerName\RootFolder\SubFolderE</Item>
</Directories>

So some questions please...

Does RTS somehow get a notification from Windows that something has changed (rather than having to check all the file timestamps)?

Realistically how many folder pairs can I put in a RTS job?

And is my idea to monitor just the required subdirectories a good idea?

Many thanks in advance.

You should just monitor the relevant subdirectories.
It makes no sense to have RTS trigger FFS caused by changes in locations that are not part of the sync.

If you run a FFS mirror or update sync, it suffices to have RTS monitor only the source (left?) location(s) of that sync.
If you need to run a FFS two-way sync, you should have RTS monitor both the left- and right-locations.
