FileFlags

Open an existing file in read-only mode or fail with IOError.NotFound.

Open an existing file in read-write mode or fail with IOError.NotFound.

Open an existing file in read-write mode or create a new file.

Create a new file, overwriting any existing one.

Create a new temporary file, overwriting any existing one.

Temporary files are deleted automatically when closed.

The file is accessed mostly sequentially.

When this flag is not present, file access is assumed to be random.

This is a hint for the underlying filesystem implementation to improve performance. It does not have any functional implications. For example, a IDataStream for a local file with the sequential hint, IDataStream.CanSeek may still return true.

Prohibits the file from being opened again, for example by other processes.

When opening the same file twice using the file flags A and B, a IOError.SharingViolation error will occur in these cases:

Bitmask of the file flags that control the creation disposition of the file other than Read.

All flags.
