The QIX format belongs to older DOS versions of Quicken, a personal finance application developed by Intuit. Quicken was available in versions for Windows and Mac, while QIX files were used by the DOS edition to store financial data.
QIX files are associated with the DOS edition of Quicken rather than current Quicken for Windows software. The format is obsolete and is no longer used for normal Quicken data storage.
Open a QIX file with the DOS version of Quicken that created it, if that software is available. The original DOS program may need to run in a compatible DOS environment.
A QIX file is not meant to be opened or edited manually. Current Quicken for Windows does not generally open this legacy format directly.
QIX files cannot generally be converted directly, and there is no reliable standalone converter for the format. If the original DOS version of Quicken can read the file, use that program's export features to move the financial data to a format supported by a newer Quicken edition.
