I just noticed that 93GB of data is being filled by .tar and installer package files in Library/.../Software Update/Data/html/content/downloads/.... folder. I have read where I can delete the packages and I have a few, but it just makes me nervous. I ended up having to find a way to allot more space on my 500GB SSD drive to allow VMWare to continue running. ( That's another story ) I was forced removed some of the .pkg files without issue. Is it ok to continue the deletion of these .tar and .pkg files? Would really be nice to reclaim the rest of the space since SSD drives are rather expensive.
Thanks in advance.
It sounds like you have turned on the Software Update Server function in Server.app if you don't need this function then you can turn it off in Server.app and then delete all the contents of that folder.
You could also reconfigure Software Update Server to only download selected updates rather than the whole lot.
Note: If you don't either disable the updates your deleting or turn off the entire Software Update Server it is likely to redownload the updates again.
If you have a second drive you could reconfigure the location used to store these updates. Probably the easiest way is to replace the folder with a link to a folder on the other drive, you would do this in Terminal.app
