open up swarm agent and change the location of your cache folder
every time you build a project it puts the build data in this folder.
the standard location is on C drive and can eat GB of space.
maximum jobs to keep is how many projects will save data
if you build a 6th this is why the first job gets removed to save space
and it removes the data from the first build job this is why you need to recompile shaders if you have not opened a
project in a long time. i have mine set to 5 because i only have 4 projects i work on.
maximum cache size is unknown. i think 10 means 100GB but i could be wrong. I just know
that my cache folder usually sits at the size 100GB I moved it to my F Drive that is an SSD.
i recommend having it on SSD so build times are faster.
Also do as @FrankieV Said about your VAULT. These are the remaining 2 parts of ue4 that stores data to your C drive.
Make sure you change the SwarmCache folder for each of your projects. open a project, build it for windows 64 or something else and swarm agent will open
or you can go into the folders and find swarm agent exe and run it.
With the vault in the launcher after you add a market place thing to your project click the remove local content to save space also. but it will require re-downloading it again to install to another project. i always remove local content tbh lol
With any GAME development you are going to require a bunch of space, for assets, sounds, built projects, test builds backups and programs for modeling/texturing/retopo and tons of other stuff. I suggest getting as many SSD’s as you can run in your pc. and upgrade your PSU because the more ssd’s/hard drives the more power consumption it will use so hope this helps
