Hi. I tried to search this topic but couldn't find exactly what I wanted. Also I'm new to this. I have a finished project in Adobe Premiere and I have a preview files folder that is over 6 GB. If I delete the preview files will this in any way damage the project? If I ever decided to go back and edit my project again will it matter if the preview files are deleted? I don't know the difference between the preview files and the actualy captured video. I have the original video that was captured from my camcorder and I'm not sure why Premiere has to make these preview files. They take up a whole lot of space, way more than the original captured video. So I guess I'm asking a couple things. 1) Can I delete my preview files, and if so, will I be able to still edit my project later on? and 2) What is the purpose of the preview files? Thanks.
