![]() This command writes a state object to the pipe containing the configuration of all filesystem watchers. NotifyFilter : FileName, DirectoryName, LastWrite To keep track of all the filesystem watchers created in the current PowerShell process, you can use the command Get-FileSystemWatcher: PS> Get-FileSystemWatcher Resume-FileSystemWatcher -SourceIdentifier "MyEvent" To suspend the notification temporarily and to resume it later the following two commands can be used: Suspend-FileSystemWatcher -SourceIdentifier "MyEvent" "TimeGenerated": "T21:39:50.4483088+01:00",Įvents raised before a handler is registered remain in the queue until you consume them using Get-Event/ Remove-Event. To produce a new event, just write some characters to a file in the watched directory: PS> "XYZ" > C:\Tempfilesxyz PowerShell allows you to register more than one handler for a single source identifier but the FSWatcherEngineEvent module doesn’t allow you to create more than one watcher using the same source identifier. Id Name PSJobTypeName State HasMoreData Location Commandġ MyEvent NotStarted False |ConvertTo-Json|Wr… The following example just writes the whole event converted to JSON to the console: PS> Register-EngineEvent -SourceIdentifier "MyEvent" -Action You can consume the event by registering an event handler for the same source identifier. The watcher now sends notifications to PowerShell’s engine event queue using the source identifier “MyEvent”. New-FileSystemWatcher -SourceIdentifier "MyEvent" -Path C:\Tempfiles Please refer to the Microsoft’s reference documentation of the FileSystemWatcher class for the details.
