Does anyone know where I can find out the layout of the files with names starting with '._' that are created when an HFS/HFS+ file is copied to a UFS, NFS etc file system?
Thanks

It should be the second file of an AppleDouble pair. A quick search on Google found the following link:

Thanks ... I should have guessed it would have been AppleDouble before asking the question ...
However, do you know why '._' was chosen as the prefix for the resource/finderinfo file when the specs for AppleDouble state '%' ...

The leading "." is the Unix convention for making a file invisible. I think the underscore is to help avoid name collisions. If memory serves, other Unix-based implementations that stored AppleDouble (eg., AU/X and maybe NetATalk) adopted the same naming convention.

Starting dot makes it hidden... The % is used in UNIX for introducing hexadecimal values of the character instead its graphic symbol (example, %41 instead of A). I think these are the reasons :p
