Hi

I need to insert same bytes automatically to 240 different addresses from a file but I have not found any hex editor able to do that.

Tried with Hex Editor Neo and Save/Load Selection and Copy/Paste commands but that didn't work properly (bytes get shifted).

How can I do that?

Thanks for your help!

You can make the ads go away by registering

010 Editor has 'Find and Replace' which you can use to locate a pattern and replace it with another pattern easily.



It also has a full scripting system which can be used to edit the file or read it etc.

Thanks but I don't want to replace bytes I just want to insert (not overwrite) the same bytes to many different addresses from the file. How can I do that?

I'm not quite sure I understand. In your first post you said that it wasn't working correctly with Hex Editor Neo cause the bytes get shifted. Inserting bytes is going to shift everything after it no matter what editor you use. Are you sure you are not looking to overwrite things?

Sorry for my horrible English. You are right, inserting bytes shifts other data (there is no problem with that) but I want the bytes to insert remain in their right addresses (relative addresses instead of absolute addresses?)

If I paste all of them at once with Hex Editor Neo only first one remains in the right address but the other bytes to insert end up in wrong addresses because one shifts the other.

I guess I need something to insert them automatically but one by one (not at once).

the only way to do this woud be to override the bytes when you copy your replacements.

have you tried the INSERT key before pasting?

In my view, you can do it in two ways:
1. Split the file according to your offset list, and while merging them add those bytes.
2. Maintain track of how many times you've added those bytes and add it into your offset while you go to next offset.
