An Issue importing FrameMaker document to Robohelp

Hi,

I am using FM 11 and RH 10.

I would like to understand that If the size of FrameMaker document is huge(say above 75000 KB) will that not be imported in RoboHelp?

When I tried importing a FM book to RH, 3 units(FM files) were not being imported. All these 3 units are relatively huge in size compared to other files in the book. It is because images are directly copied to these files and not imported by reference.

I tried the link approach too. Even there these 3 files are not getting updated.

I want to know that if the size of the file can cause such issue and if so, is there any solution other than deleting all the images and importing them by reference.

Thanks in advance.
