I heard from a loyal reader the other day. He had created a CorelDRAW file bigger than 2 GB. The file was loaded with images in the form of contact sheets. Now the file won’t open, won’t import and the user wanted to know how to recover the data within.
It isn’t the answer that anyone wants to hear, but the reality is that the file is lost forever. Remember that CorelDRAW files are compressed. So a 2 GB file on disk could be 2-5 times that big when uncompressed. Windows just can’t deal with files that big.
Let’s talk more about this specific project as I was told the pages were contact sheets of images. Let’s say that each page has 30 images on it. If those images were imported from digital camera files and then sized down to a thumbnail, there is a lot more data than is needed. After placing and sizing the images, they should have been resampled down to a lower resolution. As thumbnails, they could be 2000 dpi or more. Depending on the project, the necessary resolution could be 150-300 dpi. That alone could bring down the file size dramatically.
Even a single page filled with thumbnails of high resolution images wouldn’t make a 2 GB file. I don’t know how many pages were in the file, but I’m guessing quite a few. If that’s the case, keep the number of pages in the file down to a reasonable number. For a file like this, four pages per file is more than enough.
If you have any file larger than 500 MB, you are opening yourself to the possibility of losing the file. Stay under that limit and you’ll have fewer problems. Of course I also feel that all users from rank beginners to even the most advanced user would benefit from my CorelDRAW X5 Unleashed book. It teaches you the proper techniques for file creation and output.
