You are not giving enough informations. Where does the Tempfiles comes from?
What are you doing which create these Tempfiles?
Are these Tempfiles httpjob-downloads? If so then you probably forget to Release the Job!?

Upload a example project which shows the Issue.

Looks like it is a Java 8 and 9 issue that may have been fixed with later updates of 8 and 9.

If not, may need to investigate using Java 11 (OpenJDK/OpenJFX) (Use link provided on B4J's home page https://www.b4x.com/b4j.html)

Hmm, sorry. I´m out of Ideas.
I do not care about temp-files.

I also checked my Tempfolder (just curious). I do not have any single fxXXXXX.tmp file there...

Are you doing anything with fonts in your software?

Release mode? Debug mode?

Have you tried with a different font file? There are lots of royalty free ones about.

The one you are using is a licensed full Unicode font, hence the 22MB, if you only display letters and numbers, could you not use a smaller TTF font, this may not remove the problem but will certainly help with disk space usage.

Sure....I check by changing font and give feedback to forum...Thanks for your help..

Solved....The problem was due to font ArielUNI....it is making a temporary file every time when displaying a new question...By changing font type....this problem is eliminated...Thanks specially @don,@OliverA AND @Daestrum to come out from this problem...Thanks..B4X....a wonderful community..
