When you save a CorelDRAW file, use the check box next to the Save As window to not embed the color profiles. Also, if you save the file for the web, change the resolution to 72/96dpi and if you save it for printing, change it to 300dpi. Check the official forum for further solutions. If you already have the CDR file, you can compress it using a utility from the Software Informer database. Personally, I recommend WinRAR, WinZip and 7-Zip. Also, you can try CDR Viewer. Besides the reading tools, it has a resizing option.
