You're here because you have a file that has a file extension ending in .aiv. Files with the file extension .aiv can only be launched by certain applications. It's possible that .aiv files are data files rather than documents or media, which means they're not meant to be viewed at all.

An AIVault data file can be created using the AIVault application, and when saving these data files, the .aiv extension is the default format used for output files created with this application. These AIV data files contain text content referred to as memos or comments entered by the user of the AIVault program for a project created by the user. The AIVault application references the data stored in these AIV files when the user opens the AIV file to view its content or for editing purposes. The AIVault software is a program used to enter memos or reminders in text format, and the features integrated into this application provide users with a more convenient means of organizing, tracking and managing these memos. EllaZ Systems developed the AIValut application for users of computers running on Microsoft Windows. The content of these AIV files are encoded in binary format, and files with the .aiv extension can usually be found in a folder labeled "Memos" inside the directory where the application and its associated files were saved upon program installation.

Launch a .aiv file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .aiv file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .aiv files aren't yet associated with it. In this case, when you try to open a .aiv file, you can tell Windows which application is the correct one for that file. From then on, opening a  .aiv file will open the correct application.

Be careful not to rename the extension on .aiv files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .aiv. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
