@EleniHadjicostas, if you're working from a drive on a server somewhere, then you could possibly see if there are previous versions of the windows folder the data is sat in?
1. Right mouse click on the parent folder where the data is sat, select properties.
2. If the drive is on a server and data backups exist, you may be able to access the folder as a previous version:
