VS starts up in the wrong folder

Question

I have been using VSC for some time but lately something strange is going on. When I start it up, it says the following in the Terminal: “PS C:\Users\User\OneDrive\Desktop\flask\hello_flask>”

1. Why does it say “PS” in the beginning?
2. Why does it go to “Desktop\flask\hello_flask” by default?

Then, why I try to run a simple code (by clicking the green “Run Python in file”-button on the upper right) like this:

a = 5

b = 4

c = a + b

print (c)
in test.py file in a different folder, this is the message I am getting

PS C:\Users\User\OneDrive\Desktop\flask\hello_flask> conda activate C:\Users\User\anaconda3
conda : The term 'conda' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

At line:1 char:1
+ conda activate C:\Users\User\anaconda3
+ ~~~~~
    + CategoryInfo          : ObjectNotFound: (conda:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

However, at some, it does give me the right answer: 9

3. Why am I getting all these messages?

When I select the five lines of code (four-line, one line is empty before the print) and select “Shift-enter”, this is what it gives me:

>>> a = 5

>>> b = 4

>>> c = a + b

>>> print (c)

9

>>>

4. What do the three “>” signs mean, please?
