"The file format Is invalid" playing large AVI file


When you try to play a large audio-video interleave (AVI) file, you may receive the following error message:

The file format is invalid.


This error message can occur when you try to play an AVI file that is larger than 2 gigabytes (GB) in size. Limitations exist with Microsoft Video for Windows solutions that limit AVI files to the same maximum file size as the FAT16 file system, which is 2 GB minus 1 byte.

On computers using the FAT32 file system, the maximum file size is 4 GB minus 1 byte, which is larger than Video for Windows is designed to handle. AVI files created by Video for Windows that exceed 2 GB in size appear invalid or damaged to AVI file players.


When you are using Video for Windows-based programs, limit the size of AVI files that you create to less than 2 GB.

More Information

Programs using Microsoft DirectShow can create AVI files that exceed 2 GB in size on computers using the FAT32 or NTFS file system.
