"Download sentinel data" operator error

Hello all,

In “Download sentinel data” operator, I set a directory for download products and I have encountered errors:

I set directory as <D:\Research\ET\sat_images > and I got this error message:

ERROR:[Errno 2] No such file or directory: 'D:\\Research\\ET\\sat_images\\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800.zip'

Then I created a file named as <S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800> and I set directory as <D:\Research\ET\sat_images\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800> and I got this error message:
```
ERROR:[Errno 2] No such file or directory: 'D:\\Research\\ET\\sat_images\\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800\\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800.zip'
```
Then I created a file named as <S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800.zip> and I set directory as <D:\Research\ET\sat_images\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800.zip> and I got this error message:
```
Error: Invalid value for "--download_path": Directory "D:\Research\ET\sat_images\S2B_MSIL2A_20190627T071629_N0212_R006_T39RUJ_20190627T114800.zip" is a file.
```

For the first two tries, even if I set the directory paths with only one backslash “”, the error message gives back the directory paths with double backslash “\”. Maybe this is the problem? I couldn’t find the solution.
I just wanted to inform you about the program installation locations. Because I install SNAP in my D drive, SenEt is installed defaultly in OS drive C, in the User directory. And I tried to download the sentinel data to D drive. Could this cause an error?

Thank you for your time and help!

Hi,
I think that this is nothing related to the paths. You are trying to download an image which is more than 1 year old. ESA has a concept of Long Term Archive, meaning that only products from one year back are kept online and others need to retrieved from the archive. The LTA was introduced after Sen-ET plugin was released so this operator does not handle archived data.

I would recommend to download the image manually from Open Access Hub or one of the DIASes, e.g. CREODIAS which keeps all historical data online. Afterwards you can continue processing with Sen-ET operators.
