This function is part of the PlayerDataStorage Interface.
Query a specific file's metadata, such as file names, size, and a MD5 hash of the data. This is not required before a file may be opened, saved, copied, or deleted. Once a file has
been queried, its metadata will be available by the EOS_PlayerDataStorage_CopyFileMetadataAtIndex and EOS_PlayerDataStorage_CopyFileMetadataByFilename functions.

This function is asynchronous; the EOS SDK guarantees that your callback (the CompletionCallback parameter) will run when the operation completes, regardless of whether it succeeds or fails. Use the void* parameter to pass any contextual information the callback may need in order to react properly. Relevant information can be copied from the EOS SDK's cache while the callback function is running. You do not need to remove the callback function.
Because this function is asynchronous, it employs a callback of type EOS_PlayerDataStorage_OnQueryFileCompleteCallback to report the results of its operation.
