What manikandane is talking about is that solidworks stores a backup file within itsself. When the name is changed, the backupfile is removed. It will reappear when filed again and grow in size.
If you are just trying to reduce the size for emailing or whatever, you might want to try to save the assembly as a parasolid, xb, file format. This is solidworks native binary format. It removes all features but maintains the geometry.
or put each part into insert mode and save...... that will get the file size down too. But with the cost of internet access (as opposed to gas prices) who cares about the size of parts and assemblies anymore?
thanks ttraser, for ur valuable tips it helps lots but
i want that file in solidworks format for only viewing purpose for web based application and parasolid format reduce the file siza but after opening that file in solidworks it increase the file size again
What version of SW are you using? File size was an issue with SW 2007 SP2.2 and earlier (back to 2006). If you are using SW 2007 SP3.0 to current 2008, file size shouldn't be an issue.
In either case, Save As to a new file name, then rename back to the desired file name. This will reduce the size of the file by the most.
If you only want people to view it try Save As, PDf, choose 3D PDF. There are options there for saving in high quality and embedding fonts; turning these off reduces the file size further. 3D PDF is great for viewing and anyone with Acrobat 8 or higher can view it.

Does your assembly have alot of Configurations? This increases an assembly file size quite a bit. I have found in this case it's easier to make seperate assemblies. Are your parts built "smart", with not alot of back and forth features? If all else fails, I use Lightweight mode,setting all parts to lightweight and only placing active the parts I want to work on. This doesn't reduce the size, only the time it takes to open, work and save, not really sure if the problem is the actual size of the assembly, or working with a large assembly. I've seen assemblies much larger than 40mg. They have to be what they have to be sometimes, you just have to approach them a little differently than others to overlook the size issue.
There is a program out there called EcoSqueeze. It is a program made specifically for SolidWorks. I downloaded it a while back and have used it a few times. It seems to work pretty good. Some of the Assemblies I work on at my job are in the neighborhood of 76 MB. Once we ran EcoSqueeze on the Assembly file and it cut the size in half.
