Tom,

It sounds strange. Perhaps you could post complete snippet of code,
then it will be easier to investigate it.

Do you mean that using file name only works like full path to root
directory \, then it's wrong. It doesn't work this way under Windows CE.

If you use only file name, it's assumed you open it from \My Documents,
which is a default data location under Windows CE.

Another thing I'd suggest to check is to see if you have built GDAL with
 GTiff driver, means check if the GTiff driver is properly registered
and available, in run-time.

p.s. Please, use Reply To All, so gdal-dev address is included.
Otherwise, you reply only to post author, me in this case,
but not the list.
