how i can convert a file arch00 (lTAR) or arch00 (LTAX) to Arch00 (PTAR) any help please

Basically what you want is an arch0 ptar rebuilder.
I really doubt someone did or plans to do something similar first because the format is far from being simple and then because there are for sure many issues in doing a conversion like that.

Just curious, why you need something similar?
