SEN2COR tool


Dear SNAP Users,
I need some help regarding the Atmospheric Correction of Sentinel 2 data!
I am using ESA SNAP 6.0 (with sen2cor plug-in) for the Atmospheric Correction.
The image, I want to process is from 2015 and it’s showing the Error “L1C user product directory must match the following mask: S2?_MSIL1C*.SAFE but is: S2A_OP~1.SAF”; which is not happening for the recent images (e.g. images acquired in 2018)!
I know this issue is because of the long file name!
And I tried to change the file name as suggested in the Error message, but then also it’s showing Error “Product metadata file cannot be read”!

Any suggestions on how to resolve these issues to do the atmospheric correction of Sentinel 2 images acquired in 2015!

Thanks in Advance.


Instead of renaming the data folder, you should move it to a directory with lesser subfolders, e.g.

The folder name after extraction should remain as it is.


Thank you so much for your response.
It’s working now.
