Local path doesn't work

Hi guys, i got a problem using local paths.

On Eclipse this line

File f = new File("sav/file.sav");

save the file in the directory sav inside MyProject. So i have MyProject/sav/file.sav

Intellij instead creates two directories MyProject:

the first contains 3 other directories: out, .idea and MyProject.

So i have MyProject/MyProject/sav/file.sav

So my code works only if i do:

File f = new File("MyProject/sav/file.sav");

How can i solve this?

Thank you in advance
