I am the I.T. Manager for an engineering firm that also has an Environmental / GIS Dept. Over the past 12 years I have had several employees using ArcGIS ranging from version 3.3 through 9.x and then 10.x. We are currently on 10.6.1. For years all the ArcGIS users saved the ArcGIS related temp files that were written to the Windows temp folder. I was given an explanation as to why this was being done but I was never fully able to wrap my head around it. The questions I am posing are:
1. Is there any reason to save these files and for what reason?
2. Is this something that was necessary in older versions of ArcGIS and not necessary now?
My concern is if I get rid of these files then the existing project files (12 years worth) would either be inaccessible or incomplete. 12 years worth of temp files are also taking up a ton of space on my servers so I would like to get rid of them if I can.
I am not an ArcGIS user (which is probably obvious) so any guidance or info would be appreciated.
