sorry @marpet, maybe I wasn’t clear enough.
I had lots of sentinel-2 products (.SAFE) contained in a folder named “mydata_sentinel_2”. Inside the same “mydata_sentinel2” folder I had other files (eg: .tif .xml .R) and other subfolders.
After the deleting process of some (not all) sentinel-2 products (.SAFE), all the “mydata_sentinel_2” folder was deleted with all the sentinel-2 products (.SAFE), files (eg: .tif .xml .R) and subfolders.
