Rebuild is a file management utility invoked from the command prompt which enables you to: 
	 
 
	  
		- Reorganize an indexed file 
		
- Rebuild a corrupt indexed file 
		
- Convert files from one organization to another 
		
- Validate an indexed file 
		
The operation performed on a file by Rebuild depends on the options specified on the Rebuild command line. 
	 
 
	 Note:  
		 
		  -  If you are using Fileshare to access files, you should use only the Rebuild options that are supported for use through Fileshare. Otherwise, you will obtain undefined results. 
		  
- When working with striped IDXFORMAT "8" files, you should ensure that: 
			  
				- All stripes are present 
				
- Rebuild picks up the File Handler configuration file 
				  extfh.cfg file. 
				
 Failure to do this can lead to unpredictable results.
- You should always take a backup copy of a file before you reorganize, rebuild or convert it. This is simply as a precaution against an incorrectly specified command line which could lead to file corruption. For indexed files, you should save both the index and data parts of the file. 
		  
- Key offsets start at 1. 
		  
- All temporary files are created in the system temporary file directory, unless you set 
			 TMP or TEMP to point to the directory where you would like to keep temporary files.
