Interactive Disassembler database file
File type: Various data file
An id0 file is a database component created by Interactive Disassembler (IDA), a software reverse-engineering and disassembly tool.
It is normally used together with the other files that make up an IDA database.

The id0 file extension is associated with Interactive Disassembler, developed by Hex-Rays for Microsoft Windows. IDA analyzes executable files and stores the results in a database for later work.
An id0 file contains part of the database produced by IDA, including information used to preserve the disassembler's analysis. It is not usually a standalone document; related IDA database files may be required.
The id0 format is associated mainly with older, multi-file IDA databases. Newer IDA versions use other database formats in some configurations, so current installations may not create id0 files.
Open an id0 file with the version of Interactive Disassembler that created it. Because it is a component of an IDA database, keep it with its related database files and open the database through IDA rather than treating the file as a text document.
On Microsoft Windows, install Interactive Disassembler and use its database-opening workflow. Compatibility with older databases can depend on the IDA version.
An id0 file is not intended for conversion to a general-purpose file format, and standalone conversion tools are not normally available.
Use a compatible version of Interactive Disassembler to open the associated database and save or upgrade it to the database format supported by that version. IDA can also export selected analysis results, such as disassembly listings, when a text or report format is required.
