Don't compare paths. Use APIs like FSCompareFSRefs() or call -[NSFileManager attributesOfItemAtPath:error:] and compare the NSFileDeviceIdentifier and NSFileSystemFileNumber keys (this is the Cocoa equivalent of calling stat(2) and comparing st_dev and st_ino). > Is there any way to know whether or not a file is on a case-sensitive volume? A couple of ways (there are others): On 10.6 and later, see NSURL's new resource-values APIs and NSURLVolumeSupportsCaseSensitiveNamesKey. On 10.3 and later, see getattrlist and VOL_CAP_FMT_CASE_SENSITIVE.
