Hi,

I am creating a MSI that has two features, each containing one component. The 
user can install either or both the features. Each component use the same 
source file which is to be installed to a different location.

Although the component use the same source file, it seems the file size of the 
MSI is still doubled. If in the wxs, I remove one component totally, then the 
size is only about the size of 1 times the source file, instead of twice.

Is there any to reduce the size of the MSI in such a scenario?

Here is a sample that I have tried:

    <Directory Id='TARGETDIR' Name='SourceDir'>
      <Directory Id='ProgramFilesFolder' Name='PFiles'>
          <Directory Id='INSTALLDIR' Name='Foobar 1.0'>
            <Directory Id='DIR1' Name='DIR1'>
              <Component Id='HelperLibrary1' 
Guid='1026cf9e-946c-445e-889a-d0e947796847'>
                <File Id='Helper1' Name='Helper1.zip' DiskId='1' 
Source=MyFile.zip' />
              </Component>
            </Directory>
            <Directory Id='DIR2' Name='DIR2'>
              <Component Id='HelperLibrary2' 
Guid='33333333-946c-445e-889a-d0e947796847'>
                <File Id='Helper2' Name='Helper2.zip' DiskId='1' Source= 
MyFile.zip' />
              </Component>
            </Directory>
          </Directory>
      </Directory>
    </Directory>

    <Feature Id='Complete' Level='1'>
      <Feature Id='SomeFeature1' Level='1' AllowAdvertise='no' Absent='allow'>
        <ComponentRef Id='HelperLibrary1'/>
      </Feature>
      <Feature Id='SomeFeature2' Level='1' AllowAdvertise='no' Absent='allow'>
        <ComponentRef Id='HelperLibrary2' />
      </Feature>
    </Feature>

Thanks for your help.

Regards,
Hongping
