Assets folder 312MB Library/metadata folder 1347MB

Questions & Answers

my Assets folder has 312MB while Library/metadata folder has 1347MB

  1. is there way how to make metadata folder smaller?
  2. what happens if i completely delete it? (i tried and unity crashed, so i returned the folder back)

the project is in prototype stage and it’s planned it will have like 300x more of data in assets folder so i wonder what size of metadata will be when we’ll be working with final graphics etc.

  1. No
  2. Unity will reimport all of the assets and the project will rebuild the next time it is launched, if the ‘metadata’ folder is deleted.

It will not help to cut down the file size, as the folder will re-create and grow to about the same size. (According to my personal experience)

im guessing here but i believe the Meta data folder is something of a behind the scenes dataholder for everything u might happen to create in unity, i think it could be affected largely by Materials data as when i created a new project and deleted my material folder Mine was reduced by a sum that greatly exceeded the size of the materials folder, again its guesswork but i think reducing overall clutter throughout the project(any unnescessary materials scripts etc) will also bring down the meta data folder, give that its size appears consistant to the content held.
