Took an image and created two VCs. Exported the sidecar and edited its content in a text editor.
Imported the sidecar and it brought back the VCs with the names I put in the sidecar.
Original file name ended in 8866, I added a 1, 2 and 3 respectively and I got file names ending with 88661, 88662 and 88663 on both the raw and exported files.
For a complete rename, the sidecar’s content must be edited too.
