My apologies if this has been answered before but isn't there a simple way to get the file size as it shows under Size in Finder without using Carbon and without enumerating the directory? My understanding is NSFileSize will not do it?
I use something like this to get the total size of the data + resource forks for a bunch of paths. If the paths contain a large number of files, you can run it on a separate thread so it doesn't block the UI.
- (void) totalSizeAndCountAt:(NSArray *)paths {
unsigned long long totalSize = 0, fileCount = 0;
NSFileManager *fmgr = [NSFileManager new]; // on mainThread, you can
use defaultManager
NSDirectoryEnumerator *e;
for (NSString *path in paths) {
if ([fmgr isDirAtPath:path] && ![fmgr isSymLinkAtPath:path]) {
e = [fmgr enumeratorAtPath:path];
for (NSString *subPath in e) {
totalSize += [fmgr totalSizeAtFilePath:[path
stringByAppendingPathComponent:subPath]];
fileCount++;
}
} else {
totalSize = [fmgr totalSizeAtFilePath:path];
fileCount++;
}
}
// do something with fileCount and totalSize here, e.g., notify a
delegate on the main thread to display the results
}
- (unsigned long long) totalSizeAtFilePath:(NSString *)path {
unsigned long long size = 0;
Boolean isDirectory;
FSCatalogInfo info;
FSRef ref;
OSStatus status;
OSErr err;
status = FSPathMakeRef((const unsigned char*)[path
fileSystemRepresentation], &ref, &isDirectory);
if (status == noErr) {
err = FSGetCatalogInfo(&ref, kFSCatInfoDataSizes |
kFSCatInfoRsrcSizes, &info, NULL, NULL, NULL);
if (err == noErr)
size = info.dataLogicalSize + info.rsrcLogicalSize;
}
return size;
}
