Delete temp folder

Hi Folks,

We are on JDE 9.0 Application release with TR 9.1.5.5 windows 64-bit 2012R2, my queries is whether we can delete temp folder located at \JDEdwards\E900\ while JDE services are on? temp folder size increased drastically in a single night so we just wanted to check if we can delete files under temp folder while services are on and whether user will face any issue while doing that?

Thanks in advance.
