These files were used as data resources by web applications.

Record marked as obsolete and not updated for a long time.
The ia file extension was used for Internet Archive data resources associated with web applications. The file format is obsolete and is no longer generally supported.
Because the format is no longer maintained, its contents may depend on the web application that created it.
There is no generally supported application for opening an ia file. If the file came from an older web application, the original application or service may be required to interpret it.
A text editor may reveal readable metadata or other text, but it may not correctly display the complete contents.
There is no known general-purpose converter for the obsolete Internet Archive format. Conversion is possible only if the original web application can still read the file and export its data to another format.

Except for the digital photograph, the file also includes all the additional metadata information about the time, position and other conditions (light, exposure, colors etc.) recorded when the picture was taken.
