Yes to FAT32, no to ext3. See here for tools that can do it.

    ext3 does fragment (All rewritable filesystems do), but ext3 is much better at avoiding high fragmentation levels than FAT32, so chances are you'll never hit a noticeable performance penalty anyway.

    @TuxRug Unless, of course, you eat up around 90%+ of your disk. But you have bigger problems at that point...
