  • No false change notifications when a file system item is created, deleted, changed or renamed.
  • Supports .NET 6.0, 7.0.


Run the command:

# Nuget package
Install-Package FileWatcherEx


See Demo project for full details!

using FileWatcherEx;

var _fw = new FileSystemWatcherEx(@"C:\path\to\watch");

// event handlers
_fw.OnRenamed += FW_OnRenamed;
_fw.OnCreated += FW_OnCreated;
_fw.OnDeleted += FW_OnDeleted;
_fw.OnChanged += FW_OnChanged;
_fw.OnError += FW_OnError;

// thread-safe for event handlers
_fw.SynchronizingObject = this;

// start watching

void FW_OnRenamed(object sender, FileChangedEvent e)
  // do something here
