.VMLT File Extension
What is a VMLT file?
VMLT files often appear after a computer crash or a failed installation of a Windows service pack. When the correct codec is unavailable to play the PMB or WMM video project files, they are converted into a folder that contains a VMLT and .VMLF file. If this occurs, open the VMLT file with the GSpot utility, which tells you about the file and whether the codecs are installed.
NOTE: VMLT files are the same as VMLF files.
