Extension .dat

[hamoudoudou]

Juste rename .dat to .img to open them ( useful for saves folders Dogs to open in Puppy Linux)

A .dat file can be anything. Videos too.
Would checking magic number first with a command help?

[hamoudoudou]

Rename .img allows to open the door. to check what is inside.. it's like a pupsave, you will find what somebody has saved. It's my goal. perhaps somebody else will do different usage.
Of course that give me ideas. But as i am not sure , i keep them for me.
