You can use the Filesystem adapter to write data to a file in the filesystem.

Writing a File

Using the write operation of the Filesystem adapter, you can write a file to the filesystem.

Replacing the File

Specifying only data and length (optionally), you can write a complete file. If the file is already existing, it will be overwritten with the new content.

Writing Data to a Specified Position in the File

Alternatively, you can use the write operation with the position to write data to a specific position. position defines the byte position within a file to which the new content should be written. Depending on the length of the new data, this will result in a partly update of the file content, and/or an extension of the file.

Appending Data to a File

Using the append operation of the Filesystem adapter, you can append data to a file in the filesystem.

Modes

You can use the append operation with two modes:

• append
  If the mode is empty or append, the content stored in data will be appended to the end of the file specified in name. If the file does not exist, it will be created.
• overwrite
  If mode is overwrite, the file specified in name will be overwritten with the content stored in data. If the file does not exist, it will be created.
  overwrite will only be applied to the first append. For all subsequent appends (e.g. in a loop), the mode will be switched to append automatically.

Closing a File

On end of the service request, all files that have been used with the Filesystem adapter are closed automatically. In some cases, it may be helpful to manually close a file (e.g. if you want to rename or push the file).
You can close a file using the close operation of the Filesystem adapter.

The path and file name of the file you want to close can be given dynamically via input parameter name, or statically via the definitions of an alias.
