Working with File Manager
- File Manager overview
- Getting started with File Manager
- Viewing and changing data sets
  To view data stored in a supported data set, use the View Utility or the Edit Utility.
- Creating and editing templates
  For many tasks performed with File Manager, you can manipulate your view of a data set by applying a template.
- Working with the Template List
  Display a list of templates and perform actions on them.
- Filtering records with templates
- Managing data sets

- Enhancing File Manager processing
  You can enhance normal processing of a number of File Manager tasks by supplying a procedure that runs in conjunction with the File Manager process.
- Redefines criteria
  Redefines criteria can be specified for a field with a REDEFINES clause, or a field that is the target of a REDEFINES clause.
- Enhanced ISPF: Reference List, Search, Change, and PDSE Workbench
  File Manager provides several enhancements to the basic facilities that are available in an ISPF session: Enhanced Reference List, Enhanced Search, Enhanced Change, Indexed Search, and PDSE Workbench.
- File Manager Service Provider for z/OS® Connect Enterprise Edition
  File Manager Service Provider for IBM® z/OS® Connect Enterprise Edition enables client applications to access IBM Z data sources using z/OS Connect.

Tape block size considerations

File Manager can process input and output tape blocks that are larger than 64KB. The theoretical limit for a tape block is 10MB.

If you use tape blocks that are larger than 64KB (32KB for labeled tape processing), be aware that other software may not be able to process such large tape blocks. The hardware that you are using may also limit the block size.

File Manager supports LBI (Large Block Interface) for tape. Note that data sets (which require LBI) can not be allocated while using the ISPF interface. However, existing data set (or data sets) pre-allocated using JCL (in batch) may be processed for both input and output.
