NSMutableArray with file path

I have a NSMutableArray of names of files in my app documents folder. Now I want to make an array of file paths of those files which have names in the above array. How am I gonna do this? I'm having trouble solving this a开发者_StackOverflownd I couldnt think of any solutions. If you could help, I really appreciate it. Thanks a lot in advance.

NSString *filename = [someArray objectAtIndex:i];
filename = [[NSBundle mainBundle] pathForResource:@"someImage" ofType:@"jpg"];
