What is a QCC file?
A .QCC file is a data file that can belong to several different programs. Most commonly, a .QCC file is a Quickdraw Contours map data file created by Garmin devices to store depth data. A .QCC file can also be a Quality control characteristic data file used by Q-DAS statistical software. Other uses include Quasar accounting application data files, Microsoft JetDB databases for Quartz Crystal Control, and Quilt Manager Pattern Files used by QuiltEZ.
How to open QCC files?
The correct software depends on the exact file type. You can use Garmin marine plotters to load mapping data. For quality control charts, use Q-DAS applications. Accounting data files are standard ZIP archives, so you can extract them using standard archiving tools. Because .QCC has multiple possible meanings, viewer.online/qcc can analyze .QCC files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
Do not rename the .QCC extension. Changing the extension does not convert the file and might corrupt your data. If you do not know the origin of your .QCC file, use a file analyzer to read the internal file signature. Some .QCC files are JetDB databases, while others are compressed archives.
Summary
viewer.online/qcc is useful for identifying, inspecting, and understanding .QCC files without installing software or dealing with compatibility problems. It helps you quickly discover whether your file contains map data, statistical records, or a Quilt Manager Pattern File.
