I have a field of type LONGBLOB in my database, and my application effectively selects and saves my image or pdf, but curiously I regenerated my project and the images were not shown again in the application, so I decided to look for these images / pdf in the root folder since I have a folder that you configure in general options-> FileUpload.
but in this folder there are files that can not be seen.
Where do I save or how do I configure a cap for example images so that the images saved in my application are saved in perfect condition if I want to recover them later ?.
