Help S2FE, why I can't connect it to a PC properly?

[regressist]

WRONG TITLE it is an S20FE
Until now all my phones and tablets were very easily connected to a pc: plug-in / select transfer files (instead of charging) and I could move files, from the pc or to the pc like the device was an HD.
Now I try to do the same with the S20 but looks like I can only COPY from the phone to the PC, no way I can write in the phone. I thought it could be a matter of write permissions but I was not able to find any, and if so in which app? The file manager has full authorization
Do you experience the same crap? (note: I do not want to use any extra sw for this)

Thanks in advance to whomever will reply

do you have a sd card? are you trying to write on the system partition? or onto the sd carrd? what file manager are you using?

Thanks for you reply.
No SD card, I just see (from the explorer of my win10 pc) the same directories which I can see from the file manager of the phone, in the memory.
