What is a MAI file

MAI files mostly belong to MailEnable. MAI files are used by different applications, and their purpose depends on the software that created them. In most instances, they function as MailEnable log files that record server events such as email delivery, errors, and other activity in a MailEnable email system. These log files can be opened in a text editor or by a dedicated log viewer provided by MailEnable.
Other uses include:

Database Archive Index: Some MAI files are used to maintain an archive index by MariaDB tools in MySQL systems. For further details, visit the MySQL website.

Multimedia Data: Certain MAI files store movie data used by the Sony CLIE Movie Player.

Email Message Storage: A few MAI files encapsulate email messages that can be handled by Microsoft Outlook. You can read more on the Microsoft Outlook page.

FilExt.com note: Each variant uses a specific structure. Make sure you open the file using the appropriate application to view its contents correctly.

How can I open a MAI file?

You need a suitable software like MailEnable to open a MAI file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MAI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MAI file directly in the browser:. Just drag the file onto this browser window and drop it.

Sony (Video Thumbnail) by Sony Corporation of America
Found on memory sticks along with .MQV movie files. A user submitted these comments: A video thumbnail file used by the MoviePlayer program on Sony's Clie line of Palm OS PDAs. .MAI files contain a JPEG thumbnail picture along with information on the video file, such as its Title, Duration (in seconds), Date and time, Bit rate (audio and video in kbps), Dimensions (in pixels), File name and Size (in kB). The standard dimensions of the encoded JPEG picture are 80x60 pixels. The .MAI files need to be placed in the \PALM\PROGRAMS\MoviePlayer\100MQV01 folder while the video files in the \MQ_ROOT\100MQV01 folder in order for MoviePlayer to correctly show the video and its information in the movie playlist. The thumbnail in the .MAI file can be viewed with any picture viewer (e.g., IrfanView). To view/edit the video information you have to use MoviePlayer (and press on the little filmstrip icon on the left of the video). To create an .MAI file (or update the thumbnail picture in it) you have three options: 1. Use Sony's Image Converter (IC 1.0, 1.5, 2.0, 2.1) Windows program to convert videos and the matching .MAI files. In order for this to work, you need to have the folder \PALM\PROGRAMS\MoviePlayer\100MQV01 already existing on the selected media (hard drive, Memory Stick, etc.). 2. Use MoviePlayer on the PDA to create the thumbnail: while the video is playing, the player's menu contains under Thumbnail an Update command that updates the thumbnail picture. To invoke the menu, you have to play the movie and in small view use the Menu button on the silkskin or sidebar; or in full screen view press Ctrl+M to call the menu if your PDA has a keyboard. You can also update by using the Command strike and then U, as the shortcut to the Update command is /U. 3. Create the JPEG thumbnail from the original video file using ffmpeg and use lmame's website to create the .MAI file from the JPEG file. For this, use the following command line for ffmpeg: "ffmpeg.exe -y -i your_video_file -f image2 -ss number_of_the_frame -vframes 1 -s 80x60 -an name_of_jpeg_file", so for example to extract the 3rd frame from "test.avi" and create "test.jpg" use "ffmpeg.exe -y -i test.avi -f image2 -ss 3 -vframes 1 -s 80x60 -an test.jpg". And then use the following website to create the .MAI files: [see associated links]. Related links: Creation of a .MAI File From a .JPEG File

MAI file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be deduced from the file extension and the signature. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the MAI files looks like this:

The MAI file extension is not found very often and is mainly used by one program with a specific format. The two most popular formats are as follows:

75% of all MAI files use the same file format, which can be identified by the letters "Rec" at the beginning. These files are text files, so they contain words and text. MAI files can be up to 21 MB in size, but are often around 1 KB - 480 KB. The file type was developed only in the last few years. The files contain the following words: with, Received: from, From, MailEnable ESMTP; and com.
6% of all MAI files start with the bytes MOV000, which are crucial for this file format. These are binary files, so they do not contain words or text. The average file size is 1 KB with most files being between 160 bytes and 1 KB in size. Certain words are almost always found in the files, such as movdSmMa and JFIF.

All other MAI files (19%) have no uniform format. Just click the "Choose your .mai file to view" button on this page to find out what your MAI file is.
