Sometimes you might find that your saved fbr files is very large. If you are using an older version of FlashBack, this is most commonly caused by using GDI record mode. In particular, when using it to record moving video or video games.
A converter tool, which can convert GDI movies to smaller MPEG movies, can be downloaded from the following link:
To use the converter, extract the downloaded zip file to your FlashBack installation folder and then launch it using GDI2MpegConverter.exe. Select the file to be converted and enter a name for the converted file and then click the Convert button.
By converting to MPEG, the file size should be significantly reduced.
