Question about hash named files in config, resources and foundry

We have EasyBlog 3.9.15110 and noticed that we are starting to get a collection of hash-named files under media/com_easyblog/config, media/com_easyblog/resourses and media/foundry/3.1/config. I assume this is related to combining javascript files to reduce http requests.

We maintain our Joomla site through a git repository with multiple developers as well as multiple branches for qa and production. I suspect that we are generating new files for all the different server configurations.

So the questions are 1) Is it harmful if we merge these files into the different Joomla instances or 2) Can we safely just delete them and then gitignore any new ones that get created?

Thanks!
Andy
