I know a lot of you might already know this but it might be new stuff for some of you. I just did a test on one of my assemblies. Original size (on disk) of the folder containing only this assembly (as well as the parts that make it up) is 23.8 Mb. I then performed Ecosqueeze (a wonderful little program that can be found at [URL="http://www.ecocom.com"]www.ecocom.com[/URL]) on this folder . Make sure you check "Remove Solidworks preview image" as well as "Remove Solidworks display list" and start. Folder size shrank to 8.23 Mb. After that, I compressed the folder using Winrar (which can be found at [URL="http://www.winrar.com"]www.winrar.com[/URL]). From my experience Winrar usually compresses more that Winzip. Guess what... file size shrank to 2.22 Mb. This could make your project much easier to share by e-mail... Hope this helps a few Pascal Dufour
