What is a .ATI file?

The file extension .ATI is associated with the Office Accounting Updated Company File type. This file type is essentially a compressed backup of an accounting database. It is created by the software Microsoft Office Accounting, which was designed to help businesses manage their finances and integrate with online banking systems.

The .ATI file stores a backup copy of a .ATE file. The .ATE file typically contains accounting data that a company has sent to their accountant. Once the accountant updates or modifies this data, it is saved as an .ATI file. This updated file can then be sent back to the company, where it can be imported into the company's main accounting database to update their records with the latest information.

To open an .ATI file, you would need to use Microsoft Office Accounting. However, it's important to note that Microsoft Office Accounting was discontinued in 2009. This means that the software is no longer supported or updated by Microsoft, and it might be difficult to obtain or run on newer computer systems. If you have an .ATI file that you need to open, you will need to find a version of Microsoft Office Accounting that can still be installed and run on your computer. Alternatively, you might need to look for other accounting software that is capable of opening or converting .ATI files, although such compatibility is not guaranteed.
