How do I delete a file in my documents directory?

[simsimma]

Sorry I am a newb and am currently saving .gif files in my documents directory.

However, when a user deletes an object, I need to also delete the associated .gif files.

Can anyone point me to some code that will let me do that?

Create a reference to the default file manager and pass it the removeItemAtPath:error: message. In the code below, myPath is the path to the file you want to delete. The NULL value can be replaced with an NSError ** to get error info if there's any. If you do that, replace the NULL with &myNSErrorVariableName.

NSFileManager *fileManager = [NSFileManager defaultManager];
[fileManager removeItemAtPath:myPath error:NULL];

Myers, thanks for the help. I want to delete a .db file in the Apps Document Directory. Could you please show me in the "removeItemAtPath:" function how to select that exact .db file and path.

Thanks.

You can get the path to your Documents directory as follows:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectoryPath = [paths objectAtIndex:0];

You can then get the path to a specific file within the documents directory using:

NSString *myFilePath = [documentsDirectoryPath stringByAppendingPathComponent:@"whateverTheFileNameIs"];

I'm presuming that you know the name of the file you want to delete .

rames,

Thanks a lot for the advise and helpful code. I will try it out tomorrow and let you know how it goes.

rames,

I implemented your code, but it doesn't work. I believe that the error is in my project somewhere because the code you shared makes sense and should work. I will let you know when I figure it out.

Thanks.

Thanks again for your time. I figured out what was going on. We are creating another directory in the documents directory, (i.e. = \\documents\images) in which the files that I need to delete are located. I was trying to access the files in the documents directory not the secondary directory. I am trying to figure out how to access the secondary directory. I am new to low level file management and I will read through the documentation, though any help would be nice.

I actually think I figured it out. Here is my code to access the secondary directory in the documents directory.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
	NSString *documentsDirectoryPath = [paths objectAtIndex:0];
	NSString *secondaryDirectoryPath = [documentsDirectoryPath stringByAppendingPathComponent:@"secondary"];
	NSString *databaseFile = [secondaryDirectoryPath stringByAppendingPathComponent:@"database.db"];
	
	NSFileManager *fileManager = [NSFileManager defaultManager];
	[fileManager removeItemAtPath:databaseFile error:NULL];

I implemented this code within a function and everything seems to be working. thanks again for the help.
