The Open for add... command lets you select files to add to the Perforce 
  depot. (See Adding New Files 
  for more information.) You can select files by one of two methods: 
  -  By path: P4Web looks for new files in the workspace directory shown. 
    (Files that have no matching depot counterparts are considered "new".) You 
    can choose whether P4Web scans subdirectories, or just the current path level, 
    for new files to add. If you want to add files that are found a directory 
    other than workspace directory shown, first use the Path 
    Browser to navigate to the corresponding depot path, then use the Open 
    for add... command to select files. If you don't see this option on the 
    "Open for add" page, your client view mapping 
    might be the problem  see below. 
    
  
 
  -  By name: Specify the names of files to add. These files do not have 
    to exist in your workspace yet, although they must be present by the time 
    you submit them to the depot. You can list multiple 
    files in the text input area on the page. Each file must appear on its own 
    line. The files you list are assumed to be in the path shown. If you list 
    files with pathnames, the pathnames are assumed to be subdirectories of the 
    path shown. 
 
 After you've selected files to add, click "Continue" to display the Open 
  for Add page, where you can verify the files you selected, and choose options 
  for how they will be opened. 
Client view mapping
 Perforce uses your client view to figure 
  out how a file's name and location in your workspace are mapped to its name 
  and location in the depot. If you have a simple client view mapping, selecting 
  files to add is easy. However, if your client view mapping is complicated, you 
  might find that: 
- The files you select can't be opened for add
 - The files you open for add are mapped to unexpected depot locations
 - The "Select files to add" form doesn't give you the option 
    of selecting files by path
 
 You might need to edit your client spec to correct 
  the view mapping that is causing the problem.
