Clonezilla for Autopsy

Hello,

For a school project i have to clone a disk and use autopsy to investigate it.
So i cloned the disk using Clonezilla and got 4 images fore every partition.
Now i want to use that in autopsy but its not a valid .img extention. Its .dd-ptcl-img , vfat-ptcl-imgm and ntfs-ptcl-img instead of just .img. I was wondering how i can these files in autopsy or change it to the right file format.


Thank you in advance!
