PBGetCatInfoSync
returns Finder file type information from a file or folder. On HFS and HFS Plus file systems, the penalty for retrieving this metadata is minimal because it is stored in the file’s catalog node and read into memory along with the file name. However, on other file systems, this data may have to be read separately, incurring another read operation. Instead of PBGetCatInfoSync
, you should have used FSGetCatalogInfo
or PBGetCatalogInfoSync
and specified exactly which pieces of information you wanted.
