However, if you mean that you deleted a project or document from Works, I suspect that it is gone, but you may be able to use an undelete utility to try to recover a deleted file. There are a number of 3rd party product available for this purpose, but the longer you wait and write new data to the disk, the less likely it is that recovery can be performed.
