Create Archive File

Synopsis​

This operator creates an archive file object, which allows the compression of other file objects. It is only possible to create zip files at the moment. After all entries have been added, the archive file object can be stored in the filesystem.

Description​

The Create Archive File operator creates an archive file object. This object can be passed to the Add Entry to Archive File operator to add data. After all entries have been added, the archive file object can be stored on your harddisk with the Write File operator, or you can store it in the repository.

Currently this operator can only create zip files, but more archive types may be added in a later version.

Please have a look at the tutorial process to better understand the usage of this operator.

Output​

archive file​

The archive file object generated during the execution of this operator is the output of this port.

Parameters​

Buffer type​

This operator defines where the buffer for the archive file will be created. There are two possibilities:

  • file: The archive file will be created on a disk. Choose this option if you plan to create a big archive file.
  • memory: The archive file will be cached in the memory. A memory buffered archive file will usually perform faster in terms of execution time, but the complete archive must be kept in memory, which can lead to problems if large files or a large amount of files is added to the archive. Choose this option if you create rather small files or have a lot of memory.

Use default compression level​

This parameter allows you to override the default compression level. The default compression level depends on the host machine, but usually offers a reasonable trade-off between execution time and compression factor.

Compression level​

The default compression level of the created zip file is specified by this parameter. This level may be overridden in the subsequent Add Entry to Archive File operators on a per-entry base. In general, higher compression levels result also in a higher runtime.
