ddtbxxxx.tmp files in Tomcat Temp

Dear Community,

Our server team just reported that one of our servers is running low on space and there is a large number of files in the Tomcat Temp folder. Almost all of these are ddtbxxxxx.tmp files. From what I could see on line, these files should be deleted automatically when the program that created them is finished with them.  Some have been around since 2018!

Any idea if I can delete these manually, and better yet, how can I get garbage collection to clean these up.?

Many thanks in advance!
