File Management

Pathname

File management tracks file information, requests file copies, and controls disk space of files under FileServ control.

The table below lists file topics:

Topic	Page

Pathname	2-22

Links	2-22

Spanning	2-23

Clustering	2-24

Modify File Attributes	2-26

Generate Report	2-28

The directories and subdirectories under a migration point must have a full path name less than or equal to 255 characters.

Note

If a directory name is created with greater than 255 characters, the system administrator receives a caution on the console and logfile to immediately remove the directory. Files in this directory cannot be stored.

Links

FileServ supports hard links and soft links.

Note

A hard link can be created after a file is stored or the fschfiat command is performed on the file.
