I was working on Puzzle 1087 and not making any progress.

I quit that and tried to open puzzle 1089.

I created a directory called FolditLogs and created a batch file for
grabbing the error log.

C:\FolditLogs>dir *.bat
Volume in drive C is OS
Volume Serial Number is 1C39-7A7F

Directory of C:\FolditLogs
