Cannot unzip sentinel2 file

Optical Toolbox
#1

Hi there. I am not sure I picked the right category, however here is my problem.
I have been downloading these products:

S2A_MSIL2A_20200818T142741_N0214_R053_T20LNN_20200818T165705.zip
S2A_MSIL2A_20200804T144731_N0214_R139_T19MGS_20200804T171433.zip
S2A_MSIL2A_20200818T142741_N0214_R053_T20LNP_20200818T165705.zip
S2B_MSIL2A_20200730T144729_N0214_R139_T20MKB_20200730T171452.zip
S2B_MSIL2A_20200731T141739_N0214_R010_T20MRA_20200731T165043.zip
S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip

Each of them is a LTA product. So, I had to wait a while to be able to download them. Once downloaded if I try to unzip them I get:

Archive:  S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip or
        S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip.zip, and cannot find S2B_MSIL2A_20200807T141049_N0214_R110_T21LUD_20200807T164057.zip.ZIP, period.

The thing is also that each zip file is around 17 MB size while the original product for each tile is around 1 GB. Can someone explain me what is the problem here? thank you in advance

Hello @divill

The files you have are indeed the wrong size. This may well be as a result of issues in the Catalogue (various News items at https://scihub.copernicus.eu/news/ for May, 2021). You can contact eosupport@copernicus.esa.int for clarification, I think.

Cheers
