When downloading to a PDA using P-Strepla, the file comes up in the
format xxxXBW11.igc.

I am confused and have been unable to find why the file name is
different, or how it is assigned by P-Strepla if that is what is
happening.

Any guidance from someone who understands this will be greatly
appreciated.

Why worry? The igc file is valid right? I've never used Pocket
StrePla, but third party software can name these files anything they
want. Even though there is an IGC standard file name format those
developers don't have to follow that convention. The file name is
really irrelevant to anything except your peace of mind, the name is
not digitally signed you can just change it.
