I saw the File -> Load File -> Additional Binary File option and tried it out. Now I want my original IDA database back (with just one binary), but can't afford to lose the comments I have saved in it.

Is it possible to remove a binary after importing it?

  • Did you save the database? – user202729 Sep 22 '18 at 15:52
  • Yep, I saved it after doing so, however, otherwise I would have lost comments. – Numeri says Reinstate Monica Sep 22 '18 at 20:38

    You can use/write a plugin that exports/imports comments. Here is a plugin I wrote with some importing/exporting functionality you can use for inspiration: github.com/x64dbg/x64dbgida/blob/master/x64dbgida.py just reopen the file and create a new database and then import comments/labels you exported from your old database. – mrexodia Sep 23 '18 at 18:00
  • @mrexodia Make that an answer, it sounds like the easiest way to do what I want! Especially if it is actually impossible to unexport/remove the second binary. – Numeri says Reinstate Monica Sep 26 '18 at 4:14

Perhaps, the built-in function of saving data for export as an IDC script will help you. Try File -> Produce File -> Dump database to IDC script, then create new database and just run IDC script.

    He'll need to clean all IDC instructions related to the additionally loaded binary, though. – NirIzr Sep 25 '18 at 22:18
