This PowerShell script is for setting up a folder-watching mechanism and logging diagnostics. Here's what each part of the script does:

1. Define a folder to watch and application path:

   • $WatchFolder is assigned the path to a folder named Documents for Digital Signature located on the Desktop of the current user.
     • $env:Users dynamically references the system's user profile environment variable.
   • $pDocPath defines the path to an application (pDoc Signer.exe) located in the C:\Program Files (x86)\pDoc Signer\ directory.

2. Define a log file path:

   • $LogFile specifies the log file location at $env:LOCALAPPDATA\pDocWatcher\pDocWatcher.log. This log file will be used to store diagnostic messages.
     • $env:LOCALAPPDATA references the local application data directory for the current user.

3. Create the directory for logs:

   • The New-Item command creates the necessary directory for the log file if it doesn't exist (-Force option ensures it won't fail if the directory already exists).
   • Split-Path $LogFile extracts the directory portion of the log file path ($env:LOCALAPPDATA\pDocWatcher).
   • The output from this operation is piped to Out-Null to suppress the output.

4. Define a logging function:

   • Write-Log is a custom function for appending timestamped messages to the log file.
     • It takes a single parameter Message (a string).
     • (Get-Date).ToString("yyyy-MM-dd HH:mm:ss") fetches the current date and time in the format YYYY-MM-DD HH:mm:ss.
     • The message, prefixed with the timestamp, is appended to the log file specified in $LogFile using Out-File with UTF-8 encoding.

What this code does not do yet:

• It does not currently have logic to monitor the $WatchFolder or execute the $pDocPath application. That would require additional code for watching the directory (e.g., using the Register-ObjectEvent cmdlet) and triggering actions when changes occur.
