Somehow I've ended up with an Inkscape SVG file of over 300 megabytes which is now impossible to open.
I was doing a caricature using a collage of photos of each aspect of the subject's face subject (eyes, nose etc.) and drawing over the collage. It was a detailed drawing and I was creating individual hairs for the moustache, eyebrows and scalp by grouping and duplicating as appropriate (hundreds of times perhaps). It's a technique I've used successfully before with Corel Draw XIV.
All was going well and I was nearly done when Inkscape suddenly slowed down and eventually crashed. now it's reloaded but won't open the file. I had no idea the file had reached that size. What can I do?
