Notes about the INTKEY file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The INTKEY file type is primarily associated with 'Intkey' by DELTA Authors. Intkey is an interactive program for identifying a specimen by comparing its attributes with stored descriptions of taxa. The program can also be used to interrogate the stored data. Intkey can access its data and image files over the Internet. To do this, the data-set index file (see Introduction in the Intkey on-line help) or a link in a Web page must point to a special startup file, with extension (type) .ink or .intkey. The startup file tells Intkey where the data set and its associated images are to be found, and the name of the initialization file to use.
