Can't open watchgame.txt in Windows due to "file is being used by another process" error.

[cheeseonhead]

I can't open the watchgame.txt file while katago is running. Either using PowerShell's "Get-Content .\watchgame.txt -Tail 50 -Wait" function or trying to open the file in an text viewer.

This is the full error in PowerShell:

Get-Content : The process cannot access the file 'C:\Users\Cheeseonhead\workspace\Katago-dist\watchgame.txt' because it is being used by another process. At line:1 char:1

• Get-Content .\watchgame.txt -Tail 50 -Wait

• 
  + CategoryInfo          : ReadError: (C:\Users\Cheese...t\watchgame.txt:String) [Get-Content], IOException
  + FullyQualifiedErrorId : GetContentReaderIOError,Microsoft.PowerShell.Commands.GetContentCommand

ctrl c ctrl v to another file

How do I do that when I can't open the file at all?
