Disable Offline Attribute

---

Question:

Any thoughts how to disable\enable the offline caching off a share?? wntShareInfo() doesn't show this item

Answer:

There doesn't seem to be any build in WinBatch function. Here is some UNDEBUGGED code, that will get and set that attribute.

#DefineFunction UDF_GetFileAttributes(filename)
	;DWORD GetFileAttributes(
	;  LPCTSTR lpFileName
	;);
	
	;1     FILE_ATTRIBUTE_READONLY The file or directory is read-only. Applications can read the file but cannot write to it or delete it. 
	;                              In the case of a directory, applications cannot delete it. 
	;2     FILE_ATTRIBUTE_HIDDEN The file or directory is hidden. It is not included in an ordinary directory listing. 
	;4     FILE_ATTRIBUTE_SYSTEM The file or directory is part of, or is used exclusively by, the operating system. 
	;16    FILE_ATTRIBUTE_DIRECTORY The handle identifies a directory. 
	;32    FILE_ATTRIBUTE_ARCHIVE The file or directory is an archive file or directory. Applications use this attribute to mark files 
	;                             for backup or removal. 
	;64    FILE_ATTRIBUTE_DEVICE Reserved; do not use. 
	;128   FILE_ATTRIBUTE_NORMAL The file or directory has no other attributes set. This attribute is valid only if used alone. 
	;256   FILE_ATTRIBUTE_TEMPORARY The file is being used for temporary storage. File systems avoid writing data back to mass storage 
	;                               if sufficient cache memory is available, because often the application deletes the temporary file 
	;                               shortly after the handle is closed. In that case, the system can entirely avoid writing the data. 
	;                               Otherwise, the data will be written after the handle is closed. 
	;512   FILE_ATTRIBUTE_SPARSE_FILE The file is a sparse file. 
	;1024  FILE_ATTRIBUTE_REPARSE_POINT The file or directory has an associated reparse point. 
	;2048  FILE_ATTRIBUTE_COMPRESSED The file or directory is compressed. For a file, this means that all of the data in the file 
	;                                is compressed. For a directory, this means that compression is the default for newly created files and subdirectories. 
	;4096  FILE_ATTRIBUTE_OFFLINE The data of the file is not immediately available. This attribute indicates that the file data has 
	;                             been physically moved to offline storage. This attribute is used by Remote Storage, the hierarchical 
	;                             storage management software. Applications should not arbitrarily change this attribute. 
	;8192  FILE_ATTRIBUTE_NOT_CONTENT_INDEXED The file will not be indexed by the content indexing service. 
	;16384 FILE_ATTRIBUTE_ENCRYPTED The file or directory is encrypted. For a file, this means that all data streams in the file 
	;                               are encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.
