BACKUP

        case PT_FILE_KEY :

        {

            // copy files to lcoation

            NSFileManager * fileManager = [NSFileManager defaultManager];

            NSEnumerator * filesEnum = [files objectEnumerator];

            NSString * path;

            while ( path = [filesEnum nextObject] )

            {

                if ([fileManager fileExistsAtPath:path]) {

                    NSString * destination = [[[NSString alloc] initWithString:[[set locations] absolutePath] ] stringByAppendingPathComponent:[path lastPathComponent] ];

                    [fileManager copyPath:path toPath:destination handler:nil];

                } else {

                    // log to console

                    // file does not exist

                    [[LogHandler sharedInstance] message:[NSString stringWithFormat:@"Path '%@' is not a file or folder.", path]
                                                withType:LH_ERROR
                                              fromObject:self];

                }

            }

RESTORE

       
case PT_FILE_KEY :

       
{

           
// copy files to location


           NSFileManager * fileManager = [NSFileManager defaultManager];


           NSEnumerator * filesEnum = [files objectEnumerator];

                    NSString * destination = [[[NSString alloc] initWithString:[[set locations] absolutePath] ] stringByAppendingPathComponent:[path lastPathComponent] ];


                    [fileManager copyPath:path toPath:destination handler:nil];


                } else {


                    // log to console


                    // file does not exist
