What is a BLT file

BLT files mostly belong to AIM. BLT files serve several purposes depending on their source.
For example, one common use is as a AOL Instant Messenger (AIM) buddy list. In this case the file holds contact details for chat users and is used by AIM software (AIM website).
Other uses include:

Binary Large Text: Files that contain large blocks of text in binary format. Some records even note these may relate to theme data on mobile devices.

Binary Book Data File: A format for storing book content in binary form, sometimes used by e‐reading applications.

Quran Audio File Format: Files used to store audio recitations of the Quran. Some variations also reference a binary vector graphics layout, with users often directed to resources like Quran.com.

Binary Large Object Template: A game data archive format used in development environments such as BlitzBasic.

FilExt.com tip: Examine your file’s origin or try opening it with a text editor to find clues about its intended software.

How can I open a BLT file?

You need a suitable software like AIM to open a BLT 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 BLT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BLT file directly in the browser:. Just drag the file onto this browser window and drop it.

BLT format details:

If you can determine the file format, the associated program can also be determined. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the BLT files produces the following result:
