By default, eclipse and Aptana, didn’t hide .svn folders in the project listing. Follow the steps below to hide the .svn folder in Eclipse and Aptana:-
- Click on the little arrow button beside the Project window, select “Filters” from the drop down menu.

- Once the Filters window pop up, just make sure the .* is selected and click OK.

- Now the .svn folders should be hidden from your project list.
* Eclipse is a open source IDE for software developer which is free to download.



And not only the svn files/folders, but also all the hidden files actually (like .htaccess and so on…)
Unfortunately, this will also hide you .htaccess file !
