DBC File Types

This describes DBC file types for the purpose of identifying and locating data and other supporting files.

DBC data files

DBC programs generally do not require data files to be saved in a specific location. It is important that the user can locate their data and make sure it will be backed up.

DBC program	DBC program executable	Data file extension	Backup file extension (optional) *
DBC Finance	finance.exe	.df2	.dfc
DBC PortOpt	portopt.exe	.wf
DBC Debt Manager (ODBC data source specifies location)	cdmgr.exe	.db and .log	.db and .log
DBC Housing	housing.exe	.df	.dfb
DBC Student Loan	student.exe	.df	.dfb
DBC Multi-Family / Health Care	health.exe	.df	.dfb

* Optional backups are not intended to replace an organization's backup policies or practices.

Note:

• DBC installs many files that make up the program. Some of these files have the same name but different extensions (e.g. finance.inf, finance.chm, finance.dat). Deleting any of these files may negatively impact the program. These (and other) files may also be included in program updates.
• All other files distributed with DBC programs should not be deleted.

Other supporting DBC files

DBC programs read and create files to be used specifically by DBC programs. These files are used to improve the user's workflow and performance.

Report packet - report selections, ordering and parameters	.pkt

Other non-DBC specific file extensions

DBC programs can read or save information in files which are not specific to DBC. For example, DBC reports can be saved to an .html file which can be read by a Web browser or Excel.

User preferences

Users will need to update preferences on an ongoing basis when using DBC programs. User preferences are stored in the \\HKCU\Software\DBC branch of the Registry.

Except for DBC PortOpt, preferences may be backed up to a .sys file. Note, by default, Windows does not display .sys files.

To back up user preferences:

1. In the DBC program, go to Tools | Preferences (or System Preferences).
2. Hit Export.
3. Specify the location and name of a .sys file.
4. Hit Save.

To load user preferences:

1. In the DBC program, go to Tools | Preferences (or System Preferences).
2. Hit Import.
3. Specify the location and name of the .sys file. By default, Windows does not display .sys files. You should specify the location and type the name of the file (since you can't select it). Otherwise, turn on the Windows option that will allow .sys files to be displayed then select the .sys file.
4. Hit Open.
