Many, probably most, of these are chemical engineers or technicians rather than chemists per se. ,

“But, there is no way to be sure that the name of the directory will be always â€œDocumentsâ€ for all versions of the os.” Are you serious? Renaming the Documents directory in an OS iteration sounds very Microsoft. Why would anyone do that?

Here’s the proper one-liner:

[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]

I tried the following but it did work for me

FILE* testFile = fopen(path, “rb”);
if (testFile) {
NSLog(@”found file”);
}

any ideas on how to test if a file exists? I download files store them to a path I create by using.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"csv.txt"];

I would like to know if csv.txt is already there.

Thanks

The name of the directory will be the same for all languages. Only the display name is translated to the selected locale. But, there is no way to be sure that the name of the directory will be always “Documents” for all versions of the os. So, hardcoding such values is always a bad idea.

@Alex – Are you sure? Apple renames the documents directory of an app based on the language?

I would tend to go with how apple does it rather than this way. There is usually a method to their madness.

Which of course fails to work on non-English platforms as the “Documents” directory is localised to the language in question and is not always “Documents” therefore.
