My ArcMap.cache.data file is over 18 GB and I can't figure out what's causing it or how to empty it. The closest thing I could find is clearing the display cache, which I've done and it made no difference. I also found a single GeoNet thread that was a similar issue (mine doesn't involve Citrix), but it was never answered. It's not causing any issues that I know of, beyond simply taking up a significant portion of my SSD. I could, of course, simply delete or move the file and see what happens, but that doesn't answer the question of how it got so big and the proper way to handle it.
This is the full file path:C:\Users\<username>\AppData\Local\ESRI\Local Caches\BGLCacheV2\ArcMap.cache.data
Thank you for any insight!
