Closing document in a Hex Editor Neo releases all references to the opened file, optionally saves all changed made to the file, frees all memory and disk space used to maintain this file. The effect of closing a document will also be that the sharing restrictions set on the file at the time it was opened are cancelled, making it possible for other processes to open the file for writing.
Hex Editor Neo provides you with several ways of closing documents:
Right before closing the document, the editor checks if it is in modified state. In this case, you are asked whether you want to save the changes, cancel them, or abort the close operation.
The same prompt is displayed when you shut down your operating system, perform restart or log off. If you have any unsaved changes to any of the opened documents, you will be prompted whether you want to save them. This may delay the system shutdown process or even cancel it.
More information on saving changes made to documents can be found in Saving Documents section.
