As with all computer systems, housekeeping (including backing up data and deleting unwanted
files) is extremely important when working with IDEA.
Backing Up and
Restoring Data Files
You may want to back up files for a variety of reasons, such as, to transfer files to another
computer; to back up according to risk/criticality of data or because of disk space restrictions.
IDEA uses a single compound file with the file name extension *.imd (Unicode versions of IDEA use
the file name extension *.idm) to store all the information associated with a file, such as the data,
the schema, History, comments, indices, and reports.
IDEA stores each of these files in its project. However, the view files, equation files, definition files,
and any text files created are not stored within the compound file.
The following list outlines the file type, the location and file name extensions (ASCII and Unicode).In
order to backup IDEA Server project files, please contact your IDEA Server Administrator.
