Introduction

With this app, you can monitor seven folders without any CPU loss .. and add up to seven folders to mirror in real time!

This application can also manage directories and subdirectories and the operations Add, Delete, Edit etc.

The solution uses the WatchFolder class from the .NET Framework.

watchfolder.Path = source12.Text
watchfolder.Filter = "*.*" ' filter1.Text
watchfolder.NotifyFilter = IO.NotifyFilters.DirectoryName
watchfolder.NotifyFilter = watchfolder.NotifyFilter Or IO.NotifyFilters.FileName
watchfolder.NotifyFilter = watchfolder.NotifyFilter Or IO.NotifyFilters.Attributes
watchfolder.IncludeSubdirectories = True
AddHandler watchfolder.Renamed, AddressOf logchanger
