We have SDL Web 8 Content Delivery Services (Deployer and Content Micro Services) installed on a Windows 2012 server. Today we noticed over 50Gb of files in the `C:\Windows\Temp` folder which are in sub folders with names like `tomcat.4399394087417898973.8084`. These in turn have the following folder structure:

```
"C:\Windows\Temp\tomcat.4399394087417898973.8084\work\Tomcat\localhost\ROOT"

```

Inside that folder we see a lot of .tmp files. It seems like the deployer or storage classes may be creating these files (maybe instead of the old transactions folders in the deployer?), but they don't seem to get cleaned up.

So my question is two-fold
1) What is making these files, and should they be automatically cleaned up?
2) Can I use a script to clean them up, and if so what criteria should I use for deciding if each .tmp file is deleted?

Thanks in advance for any advice you can offer.
