Large .grb file that won't open in O...

The French hydro service (SHOM) has started distributing very fine-grained .grb files (0,01° !!! - every hour) from the Arome model of the French met office (Meteo-France) in a convenient format (as opposed to the grib2 format of the original). They cover from Ireland to Galicia and North Sea to Sardinia
They are huge (about 250 Go for a single day).
DATA.SHOM.FR
Select 'Vitesse and Direction du vent' for a date and hit 'Télécharger source des données'
I have uploaded an example here
DL.FREE.FR
(valid one month)
These files crash Zygrib and O 4.0, not 4.2 but nothing is displayed
They display fine with Squid 8.3.0 and Qtvlm 5.3.0 though

Could a kind soul make the grib plugin able to display those mammoth files (If that is the problem...)

PS an xml file is available

The file you uploaded crashes Ugrib, too.

Has this been fixed in the recent beta versions?

Re: Large .grb file that won't open in O...

I tried the 120mb file with Windows v4.2.1724 it "can't be read.
Then tried downloading something smaller by zooming in and having a smaller area, when I went to download by clicking on the area as it says, it was stilll 120mb.

I must be doing something wrong with the website, but I don't think grib_pi is working with these files yet.
