What Makes up a DRP File?

Hell everyone, was wondering if anyone knew the answer to what's inside a .DRP file? I've recently had horrible issues with Da Vinci Resolve Studio opening projects excruciatingly slow. (20-30min) Once I exported a project I noticed that the file was 231MB in size and when I imported this same file into my MacBook and exported a fresh version it shrunk to 41MB. I presume this was part of the issue as it seems to be opening quickly again. It just seemed so bizarre to me that the file shrunk so much.

On another note, someone with Blackmagic had been helping me and its been almost 3 weeks with no response after 3 emails of checking in with them. I also put in a new support request with zero response. Hopefully I've solved this issue after re-installing Resolve and creating a new database but just in case this issue comes back was hoping someone at Blackmagic can finally get back to me. thank you.

If you export the DRP with stills and thumbnails, the file will be significantly larger and slower to import/export than if you exported the project without them.

My guess is that you had either of those options enabled when you did the initial export of the DRP, but on your MacBook, either of those options were not enabled when you re-exported the same project.
