"of" usage (All of my projects can be downloaded from here)

[dama]

I've been searching on the internet about usage of "of" in some sentences and I couldn't find anything about it.

What is correct?
1) All my projects can be downloaded from here. (it refers on my website)
2) All of my projects can be downloaded from here.

Could you explain, please?

Hi, dama.

I'am not a native speaker, but in my opinion both are correct. As I have read when you use 'all of' you must then use the / this / that / these / those / my / your / his etc.
So, you can't write:'All of projects', but 'All of MY projects' is correct.
