File already open


Updated: July 20, 2015

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

Sometimes a file must be closed before another FileOpen or other operation can occur. Among the possible causes of this error are:

  • A sequential output mode FileOpen operation was executed for a file that is already open

  • A statement refers to an open file.

To correct this error

  1. Close the file before executing the statement.
