Is there an opensource application/software out there that can open and manipulate .ai (adobe illustrator) files? Someone asked me and I couldnt think of any to suggest.
Well inkscape is capable to open and edit AI files but it needs an extention www.inkscape.org/ And for edit Photoshop files you can use http://www.gimp.org Both are excellent open sourse editors one for vectors and the other for bitmaps hope it helps
