In my program I have to read data from a large number of hdf5 files with a fixed size (3307) ascii header added. For now, I loop through the files and write a temporary file to disk without the disturbing ascii header and then use HDF5.jl to read what I need.

This works fine, but I guess (hope) there should be a faster way, avoiding this extra writing and reading from disk?
