Cleaning .txt in Documents folder

Question

I am adding .txt file to Documents folder for storing some data using solution founded here: Read Text File in Document Folder - Iphone SDK

So now I can write and read text from this file succesfully, but I need also to have action what will clear all text in this file to make it absolutely empty. Is it possible?

well, the simplest way would be to delete the file then create a new one with the same name. you can use [this tutorial](http://mobiledevelopertips.com/data-file-management/iphone-file-system-creating-renaming-and-deleting-files.html) to learn how to do that. — Oren, Feb 03 '13 at 16:30

In one line, this ought to do it:

[[NSData data] writeToFile: pathToFile atomically: YES];

This will loop all files -in Documents Directory- which has suffix of "txt" and delete its contents:

NSString* path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSArray *arr = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:nil];
for (NSString *fileName in arr) {
    if ([fileName hasSuffix:@".txt"])
    {
        [@"" writeToFile:[path stringByAppendingPathComponent:fileName] atomically:YES encoding:NSUTF8StringEncoding error:nil];
    }
}

As of iOS 8, do **not** use this to get the Documents folder. It is no longer just off of the "home" directory. — rmaddy, Aug 13 '15 at 00:36
