#1 Burning Software

I saw StarBurn supported ISO9660 and Joliet format. But when I use StarBurn_ISO9660JolietFileTree_BuildImage function, it just can support 8 level. If the tree level is exceed, the burnt directory will be error. Any other tech or API can make it correct.

You need to pass TRUE as IsLevel2 parameter during file tree creation. See this API call:

STARBURN_IMPEX_API
EXCEPTION_NUMBER
__stdcall
StarBurn_ISO9660JolietFileTree_Create(
OUT PVOID *p__PPVOID__ISO9660JolietFileTree,
OUT PCHAR p__PCHAR__ExceptionText,
IN ULONG p__ULONG__ExceptionTextSizeInUCHARs,
OUT PULONG p__PULONG__SystemError,
IN PCALLBACK p__PCALLBACK,
IN PVOID p__PVOID__CallbackContext,
IN BOOLEAN p__BOOLEAN__IsInvalidKidIgnore,
IN BOOLEAN p__BOOLEAN__IsLocked,
IN BOOLEAN p__BOOLEAN__IsLevel2,
IN FILE_TREE p__FILE_TREE
);

I have passed TRUE as IsLevel2 parameter during file tree creation. When I use StarBurn_ISO9660JolietFileTree_BuildImage, the burning result will be error. Some files will be incorrect directory. Because the tree level exceeds 8. Strange, some thime, it will be right when the level exceeds 8. But some time, it will be error. I found when the directory length is long, it will be error. In fact, the length is not very long.

Path is too long. If it's too long particular file name will be rejected. You get an informatical callback so you could be able to inject this file later using shorter ISO9660/Joliet structure. Everything works as expected.

How to make the name is shorter? what API function can be called? Can you give me a simple example? Thanks.

Catch CN_FILE_TREE_PROGRESS_IGNORE callback and keep some kind of the list. After you'll build the tree do call Add(...) again passing shorter name as RootDirectoryNewName.
