Opens the storage.


    procedure Open(OpenMode: TStorageOpenMode);

[Plain C]
    long _stdcall StorageOpen(const wchar_t* FileName, unsigned long* Storage, wchar_t PathSeparator, char UseTransactions, char UseAccessTime);

[C++ (DLL/Lib)]
    void Open(StorageOpenMode OpenMode);

[C++ (VCL)]
    void Open(TStorageOpenMode OpenMode);

[C++ (.NET)]
    void Open(StorageOpenMode OpenMode);

    void Open(StorageOpenMode OpenMode);

    Sub Open(OpenMode As StorageOpenMode)

    void open(StorageOpenMode openMode);


  • OpenMode - specifies the mode in which the storage is opened.
  • [Plain C] Storage - returns handle to the opened SolFSStorage.
  • [Plain C] FileName - specifies the name of the storage file on physical media.
  • [Plain C] PathSeparator - specifies the separator which will be used in further storage operations.
  • [Plain C] UseTranactions - set this parameter to True to enable transactions and journalling. Note, that transactions slow down file write operations significantly.
  • [Plain C] UseAccessTime - defines whether last access time is written to storage when the file/folder is accessed. Writing access time slows down the operations.

Values of StorageOpenMode

[Plain C]  Return values

0 if the function succeeded or one of Error codes if the function failed.


Use this method to open or create SolFS storage. All parameters are taken from the properties which must have set before.

If the storage (container file) has ReadOnly attribute on the disk, you should open it in read-only mode. Attempts to open such storage in Read-Write mode will fail.
