Library Files

The following files are stored in the public Application Data repository, C:\Documents and Settings\All Users\Application Data\Convergent Computations\Geoida (Windows 2000/XP) or C:\ProgramData\Convergent Computations\Geoida (Windows Vista/7):

Definitions.gld - Definitions library database
Geoida.ini - Geoida configuration
girfsup2.dll - ActiveX extension library
username.ini - Current user's configuration and definitions

Data Files

The following files are stored in the current data folder (normally My Documents\Geoida\Data ) - the location of data files (or jobs) is user-definable and may be changed or selected as required:

jobname.gdb - Job database - Backup of compressed or repaired job database (Repair Job option)
jobname.gdb.bak1 - Current backup of job database
jobname.gdb.bak2 - Previous backup of job database

The following data files are plain text format:

jobname.&nn - Extracted control observations (Extract file); nn = Traverse or data ref. number
jobname.csv - Extracted control observations (CSV Extract file)
jobname.CSV - CSV raw observations export
jobname.PLT - Screen-plot - Options other than Traverse or LS Network Adjustment*
jobname.Pnn - Screen-plot - Traverse or LS Network Adjustment, set #nn *

It is essential that files relating to each job be backed up onto a suitable device if you wish to retain data for future reference or recovery following a system failure or corruption. Files deleted manually from the Geoida data area will normally be retained in the Windows 'Recycle Bin' until it is emptied. Geoida makes a backup to the current data folder when opening an existing job database and also if the Repair Job option is used. Refer also to Backups about the necessity of ensuring that a reliable backup procedure is in place.

List Files

The following files (all ASCII text) are stored in the current list-files folder (normally My Documents\Geoida 5\List ) - the relationship of the List path to other Geoida folders is set in Preferences:
