Sub IsSolFSStorage()
Parameters
- FileName - [DLL] - the name of storage file.
- delegates (event handlers) - see corresponding delegate/event type description.
Return value
True if specified file seems to be a valid SolFS storage and False if not.
[DLL] 0 if the function succeeded or one of Error codes if the function failed.
Description
Use IsSolFSStorage to check if the file is a valid SolFS storage, without actually opening the storage.
In all interfaces except DLL/Lib the name of the storage file must be set using FileName property before calling this method. In DLL/Lib call there's a Filename parameter for this.
The method can throw exception (except DLL/Lib version) if the error other than "not a SolFS storage" happens.
Note, that this method doesn't perform CheckAndRepair operation on the storage to ensure, that the storage is completely valid. Call CheckAndRepair separately when needed.
