The logs files for PST Flight Deck are by default being written to C:\Program Files (x86)\QUADROtech\Logs location.
To change default logging location, follow this steps:
1. Create a folder in the new location, eg D:\QUADROtech\Logs
2. Move the gtrace.exe file to to new QUADROtech folder; D:\QUADROtech
3. Delete “Logs” folder in C:\Program Files (x86)\QUADROtech location
6. Restart all the running PST Flight Deck services and also PSTFlightDeckWSAppPool in IIS (Internet Information Services Manager)
After performing this steps the log files will be written to new location.
