How can I reduces size of the solidworks file?
Welcome to the forum. It's difficult to answer a question that's as broad as yours. Is it an Assembly, Part, or Drawing? How large is it now?
Can you upload a copy of the file so we can give some more accurate advise?
1. Reduce the image quality.
2. If you need a really small file and do not mind triggering a rebuild upon opening it, check off this box:
3. If you have multiple configurations, purge the tessellation from all in-active configurations.
More questions from me. Why do you want it smaller? Perhaps to email the file? To temporarily reduce file size of a part model you can add a delete body feature at the end of the tree and remove all the bodies. For assemblies, you can suppress all the components.
Are you using Solidworks 2015? If you are using a version prior to SW2015, you will see significant file size reductions saving in 2015 format.
