File Management refers to to terms of working with files, manipulating them, changing their names, locations etc. When creating iOS or MAC OS apps, we can use the C-style functions for working with files.
As Objective-C is an object oriented programming language, we'll use its way, and that will be the NSFileManager class, which has a bunch of utility methods.
[NSFileManager defaultManager] will return us a NSFileManager object that we can further use.
To check if a file exists at a specific path, we use the syntax:
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
To change the file's location, we use:
[fileManager moveItemAtPath:currentPath toPath:newPath error:nil];
We can provide a NSError object as the last parameter to this function, and then use that to check if the operation involving files got successfully executed.
