There is a folder under xFlow installation \temp. For security or what ever reason, users may want to know if they can delete files from \temp or block writing to this folder.
Release : 17.3
Component : SDM - xFlow
\temp folder is an integrated part of the xFlow/Service Point apps(maybe we should not call it "temp" but something else) and none of individual file/folder can be deleted from \temp folder. If, for what ever the reason, you would need to delete something from \temp, you can delete the whole CasmPlayApi folder but you would need to re-start xFlow so CasmPlayApi can be regenerated. Also no file/folder can be blocked from this \temp. In short, the folder name "temp" may be misleading that people could think it is a temp folder that files/folders can be deleted/blocked but in reality it is part of the xFlow/SP operations and you should not touch it unless instructed by Support for some troubleshooting reason.
