The version of 16.01 according to the properties says that it is 466MB, the 16.1 download patch that they want you to replace it with is only 255MB. Why the difference?
Inside the installation files is the "Data1.cab" file. Basically, this is just a big Zip file that contains a compressed version of all the files that make up TurboCAD. In the Data1.cab file you have 3,794 files that are 485Mb (uncompressed). Most go to "C:\Program Files\IMSIDesign\TCWP16", while the rest go to "My Documents", "Application Data", etc. When the program is installed, that 255Mb of compressed
files will expand to 485Mb of uncompressed
I'm not so sure about Symbols anymore, but I believe they are called up from links in the INI file (TCExplorer); see: Template_Table. If you expand "Drawing1" under Drawings (or any drawing) you'll see what is contained in a drawing. There's no listing there for Symbols, like there is for Brush Styles. Once you get everything set up the way you like, it's a good Idea to keep a copy of "TCW16_xml.ini" somewhere outside of the "Built-In" folder. After a reinstall/repair/update and after you've run TurboCAD once, you can replace the bare-bones INI with your saved copy. Your saved copy should
have all your Symbol listings, so you won't have to set these up a second time.
Hope this helps.
