doctor temporary files

currently the doctor is creating the temporary files in the system temp folder. Is there a possibility to explicitly change that to another folder (which can be excluded from virus scan ...), otherwise we have huge performance issues at customers with strict security sttings

You have two options:

1. If the Doctor has an accessible configuration file - set the temp path.
2. If there is no accessible configuration file, or there is one with the default temp path $temp, which indicates the default system temporary path, you should be able to change that default for a JVM by running it with  -Djava.io.tmpdir=/my-temp-path.

great, thanks, was not aware of that option
