Editing files

HexEditor permits to overwrite sequences of bytes using any encoding scheme. Be very careful when using that feature as this can result in file corruption of some sort.

Entering Editing mode

To enable editing, you must check the Enable Editing checkbox (in the File box). A message will remind you that this is a dangerous operation. Click OK to proceed.

Next, after having selected some bytes sequence in the Content area, you can use the fields that normally serve for viewing, for editing by typing values in it.

Note that all editing operations are performed on the fly. They can be undone as long as the file stays open, using Undo/Redo from the Edit menu.
