Thanks Jukka and Muchaelm Probably layer property is what I look for. I am working around a plugin that exports multiple selected layers (at least vector, referencedimage and sextante raster) to a defined folder, without modifying the OJ layer tree ( ex SaveDatasetAsPlugin usually substitute the original file with the saved file on the layer tree). I already have a prototype of such plugin and I found useful in a productive context. I wanted to add a possibility to automatically divide multiple geometries in a separate primitives when saving to shape files.
