Thanks a million.

I downloaded the h4h5tools-2.2.2-win64.zip file and obtained the 
H4TOH5-2.2.2-win64.exe after decompressing.

I executed that file and installed the H4TOH5-2.2.2-win64 without any 
problem. I also downloaded the H4TOH5 Users Guide and Reference Manual.

However I am not able to make the conversion. I went to the "command" 
option of Windows, and I pasted the following:

C:\Program Files\HDF_Group\H4TOH5\2.2.2\bin\h4toh5convert.exe 
D:\Guanacos_3\Consultoria Santa Cruz\Datos SC\Clima\MODIS 
Snow\AMSR_E_L3_5DaySnow_V09_20050126.hdf

and I got the following message: "C:\Program" is not recognized a an 
internal or external command.

What do you think I am doing wrong?

Thanks again,

Jorge

It appears that you do not know how to tell Windows how to deal with a space in
your command. That not really an on topic question for R-help. You need to learn
how to use the operating system you have chosen. It might be a simple as not
using full path to your program if it is registered, or you might need to
navigate to the ?Program Files? directory, or <something else>.

You need to wrap paths that contain spaces with double quotes.  Given the way
the lines are broken in the email I can only guess you might want something like
this

"C:\Program Files\HDF_Group\H4TOH5\2.2.2\bin\h4toh5convert.exe "  
"D:\Guanacos_3\Consultoria Santa Cruz\Datos SC\Clima\MODIS
Snow\AMSR_E_L3_5DaySnow_V09_20050126.hdf"
