i tried the following
- svnadmin create svn_repos
- svn import my_first_proj file:///c:/svn_repos -m "initial import"
- svn checkout file:///c:/svn_repos
and the command returned
A    svn_repos\trunk
A    svn_repos\trunk\Sample.txt.txt
A    svn_repos\branches
A    svn_repos\branches\my_pers_branch
Checked out revision 1.
Yet the .svn folder was not created in the checked out folders.
Because of which [I guess], I'm not able to do svn  copy or svn merge.
Why does this occur? what is the problem? is there anything wrong in my commands
