cfg
Project configuration file. Stores project configuration settings. It has the same name as the project file, but with the extension .cfg.
The compiler searches for a dcc32.cfg in the compiler executable directory, then for dcc32.cfg in the current directory, and then finally for projectname.cfg in the project directory. You can therefore type:
dcc32 project1
on the command line and compile the project with all the same options as specified in the IDE. You can also type:
make -f projectgroup1.bpg
to make all the targets in the project group.
dci
Holds Code Insight changes you make in the IDE.
delphi.upg
Includes information used to upgrade packages from one version of the product to the next. It is located in the bin directory.
delphi.dct
Holds component template changes you make in the IDE.
dmt
Holds changes you make to menu templates in the IDE (may cause a "Stream Read Error" if corrupt; deleting it will lose your changes to menu templates but resolve the error).
dof
Project options file. Contains the current settings for project options, such as compiler and linker settings, directories, conditional directives, and command-line parameters. Set these options using the Project Options dialog box (Project|Options), they are saved in text form for easy maintenance, version control, and sharing.
dro
Holds changes when items are added to the repository. Can be deleted but your additions to the repository will lost. Can be restored to default by copying the original file \bin\delphi32.dro (Windows only applications) or \bin\CLXdelphi.dro (cross-platform applications) from the product CD.
dsk
Desktop settings. Saves the current state of the desktop, such as which windows are open, and in what positions. Used when Tools|Environment Options|Preferences Autosave Desktop is checked. Depending on where you're working, you'll save desktop settings for the project (Project.dsk), project group (Group.dsk), or IDE (.dsk). Delete these if you do not want to save the desktop settings.
res
