Delete a segment

 Action    name: KillSegment
 

IDA will ask your permission to disable the addresses occupied by the segment. If you allow this operation, information about the segment will be deleted. In other words, IDA will discard the information about instructions or data, comments etc.

If you check "disable addresses" checkbox, IDA will mark the addresses occupied by the segment as "nonexistent" in the program. You will lose *ALL* information, including byte values.

It is impossible to disassemble the content of adresses not located in any segment, therefore you must create a new segment if you want to resume the disassembly of that part of the code.

Also, you can edit (see below) an adjacent segment to [expand] it to those addresses.

IDA will ask your permission to disable addresses occupied by the segment. If you give your permission, ALL information about the segment will be deleted, otherwise IDA will discard information about instruction/data, comments etc, but retain byte values so that you will be able to create another segment afterwards.

To disassemble the addresses occupied by the segment you need to create a new segment again (i.e. you can't disassemble bytes without a segment). Also, you can expand another adjacent segment to these addresses.
