I got the following error when I use Sentinel-2 Level-1C image retrieved from the LTA archive to perform atm. corrections with Sen2cor :

[Errno 2] No such file or directory: ‘…\S2B_MSIL2A_20170819T154859_N9999_R054_T18SUE_20210118T162125.SAFE\GRANULE\L2A_T18SUE_A002368_20170819T160034\IMG_DATA\R20m\T18SUE_20170819T154859_B02_20m_geo.jp2’

Can I have your help please?
Best.

First off: the error is complaining about an L2A rather than an L1C image.

In any case,
I seem to remember the image names up until ~2018.03.28 had an additional prefix L2A_. So that the end of the path you need might be:

L2A_T18SUE_20170819T154859_B02_20m_geo.jp2
rather than
T18SUE_20170819T154859_B02_20m_geo.jp2
