If you use the latest file format version with a 1.8.x version of the library,
this goes down to 195 bytes. See
https://www.hdfgroup.org/HDF5/doc/RM/RM_H5P.html#Property-SetLibverBounds
>>> import h5py
>>> h5py.File('foo.h5', libver='latest').close()

Subject: [Hdf-forum] Minimum size of an HDF5 file?
Hi Everyone,
I am thinking of using HDF5 for data that is usually very small, but can
sometimes get substantial. So I am wondering what is the minimum size of an
HDF5 file? I tried running this program
#include <hdf5.h>
int main()
{
hid_t file;
file = H5Fcreate("small_hdf5.h5", H5F_ACC_TRUNC, H5P_DEFAULT, H5P_DEFAULT);
H5Fclose(file);
}
which gave me a file with 800 bytes. Is that the smallest it can get?
Thanks,
Walter Landry
