When you emptied the bin, used Shift Delete to get rid of the file, deleted it from within an application or used some other method of removing it that bypassed the bin, then it is still almost certainly recoverable. When you empty the Recycle Bin or delete a file using another method, the file is still not really deleted. The file no longer exists as far as the operating system is concerned and the space it occupied becomes available for re-use by other files. But the disk space does not get re-used straight away so the data that the deleted file contained will stay on your hard drive for some time to come.
So first things first - Stop putting more files the disk in case your deleted ones are overwritten. Only un-overwritten files are possible to be recovered with so-called data recovery software like Recuva. Or other programs such as
