Is it possible to specify the beginning and end points of the file to be opened before opening?

Is it possible to specify the beginning and end points of the file to be opened before opening? For example, if I have a file of size 1234567890 bytes and I want to open it from 2345777 to 2345888, how do I set these values before opening it, so that the program will not even try to display any data that lays outside of this range?

I do not know how EmEditor reads a file, but the program is able to display a specific fragment (from point X to point Y), and the problem is that I do not see how to set these two values before opening. If the point X is equal to the size, the program would display the last byte only. If the point X is larger than the size, the program would send the corresponding message and not display any data from the file. Otherwise, if the point Y is larger than the size, the program would display the file from point X to the end.

You can set the beginning and end points of the file in the File page of the Customize dialog box - From and To text boxes. This will change global settings, and so you will need to reset these settings before you open another file normally.
