Quicken Win version 6 file
File type: Accounting, financial and tax file
A ZKA file is a legacy financial data file used by Quicken for Windows version 6.
File type category:
Accounting, financial and tax file
Date updated: September 27, 2026
The ZKA file extension is associated with Quicken, a personal finance management tool developed by Intuit. Quicken is available in both Windows and Mac versions, but this particular format belongs to the Windows version.
Quicken for Windows version 6 used ZKA files to store financial data. The format is obsolete and is no longer normally created by current versions of Quicken.
Open a ZKA file with the compatible legacy release of Quicken for Windows, specifically Quicken version 6. Current Quicken versions do not generally open this format directly.
If the file is important, work on a copy and use the original Quicken installation or a compatible older environment to access it.
If Quicken for Windows version 6 can open the file, use its export features to save the financial data in a format such as QIF, then import that data into a compatible newer Quicken version or another finance application.
