The xFlow application uses CasmPlayApi and playtempxxxxxxx folders for caches and sometimes for troubleshooting reason, Service Desk admin would need to clear those and restart xFlow.
Due to some patch level changes the location(s) of these folders changed and this techdoc details where they are.
Release : 17.3 and higher
Component : XFLOW INTERFACE FOR SDM
Before RU4, all these playtempxxxxx and CasmPlayApi folders are under C:\Windows\Temp folder(for Windows) or /tmp directory(for Linux/AIX).
In order to improve the product application, starting from RU4, playtempxxxxx folders are still under <local drive>\Program Files\CA\xFlow\APPS\temp folder (for Windows) or /opt/CA/xFlow/APPS/temp (for Unix)
