Good morning, My name is Vladut Constandoiu, I'm a university student from Trento, Italy and I'm using QGis for my master thesis. Yesterday I had a very unpleasant experience with QGis. I have a shapefile that contains all of the different areas of the river's hydrological basin on which I'm doing my project; every element has two attributes: type (TIPO) and area (SUP). Somehow I managed to erase those attributes from the attribute table and could not do undo (ctrl+z or anything else) since the auto-save plug-in activated exatly 2 seconds after my mistake and saved the changes. The shapefile contains about 6900 elements, and they were all sorted by use, while now they are just areas without any information. Is there any way to recover a previous version of that shapefile so that I don't have to spend uncountable hours putting all the attributes back in? Here are three pictures of my work, previously and after the loss of information.
Before data loss: [image: image.png] After data loss + legend of types of area: [image: image.png] Attribute panel: [image: image.png] I would be enormously grateful to anyone who could help me find a solution. Thank you very much in advance and have a nice day. Sincerely, Vladut Constandoiu
