PSV Exporter allows you to extract files from the Playstation 3 virtual PS1 and PS2 save that is created when playing a PS1 or PS2 game on the Playstation 3.
Usage for PS2 files
Load the psv file to display a list of the files contained within. You can extract individual files or extract all at once. When you extract all at once you will be prompted to choose a location to save to. In this location a folder will created containing all the files, this maintains compatibility with uLaunchELF and PS2 save Builder (hint: The Root/ID should be named the same as this directory.)
Usage for PS1 files
Simply load the PSV file containing the PS1 save and press the PS1 button (or 'Extract PS1 save' menu item/popup menu item) and choose a name for the file. PS1 saves are extracted as .mcs files, these are a single save (as opposed to a card image ala Dexdrive). Should you need a different save format a utility such as PSXGameEdit should be of use.
