I seem to have saved the cache and conformed media cache to my desktop, which is a dumb place to put them because there's not that much space. I'm brand new to Mac. What, and where, would be the ideal folder to store the caches and have the most GBs? And please be as obvious and detailed as you can cause I'm a complete newbie to the Mac system
btw I apparently have about 47GBs available
Thanks in advance!
Put them anywhere. I have a separate folder under my User ID that I use for all disposable cash items. The other option is to just relaunch AE while mashing down on Shift + Alt/Option + Ctrl/Cmnd and delete your preferences. The default location is just fine. You never do anything with the cache files other than delete them occasionally anyway.
If you want to optimize AE's performance, it's ideal to set the Media Cache and Disk Cache to a fast secondary hard drive (a drive that ISN'T your boot drive). Maybe a small SSD, for example, connected via USB 3 or Thunderbolt. But otherwise, if you don't have an extra drive for it, you internal drive will work, as long as you purge it from time to time if you're low on space. As Rick said, it's easy enough to purge.
