Hex editor recommendation?

[terrypin]

I'm not a techie or programmer but occasionally need to edit binary files. For example, my app Macro Express Pro creates its macro files in proprietary (MXE) format. If I make changes to my Win 10 PC file/folder organisation then scores or even hundreds of macros have to be edited. For example, a macro script command that contains the string C:\xyz\abc might need changing to D:\wxyz\abcd.

I have the handy freeware program HxD, which lets me make changes of the same length (such as changing C:\abc to D:\def) but I'm looking for a program that will achieve those more complex edits.

Does anyone here use such a program that they can recommend please?
