### Remarks

A truncated read occurs when the [ReadCommand](/engine/6000.5/script-reference/unity/io/lowlevel/unsafe/readcommand.md) describing the read operation specifies a `Size` and `Offset` that extends past the end of the target file. After the read operation is complete, use [ReadHandle.GetBytesRead](/engine/6000.5/script-reference/unity/io/lowlevel/unsafe/readhandle/getbytesread.md) to get the total number of bytes read for a request, or GetBytesReadAtIndex to get the number of bytes read for a single [ReadCommand](/engine/6000.5/script-reference/unity/io/lowlevel/unsafe/readcommand.md). A truncated read does not typically indicate a problem; all data in the file is read and no extra bytes are copied to your read buffer.
