VFSExplorerImpl.cpp@ 57151

最後變更在這個檔案從57151是 55611,由 vboxsync 提交於 10 年前
Main: Merged the VFSFileType and FsObjType enums, keeping the 'FsObjType' name while picking the values and most of the names from VFSFileType (because they make more sense to someone who came up with the RTFS_TYPE_XXX and RTDIRENTRYTYPE_XXX bits). VFSFileType used 'SymLink', that's not 'Symlink' in keeping with the rest of the API and IPRT.
