Visiting this page should help you answer specifically these, or similar questions:

  • How to open files with DPR extension?
  • How can I convert a DPR file to a different format?
  • What is the DPR file format extension?
  • What programs support the DPR file?

If after viewing the stuff on this site, you have still not received a satisfactory answer to any of the above questions, this means that the information regarding the DPR file presented here is not complete. Contact us using the contact form and write what information you did not find.

What else could be causing the problem?

There may be more reasons why you cannot open a DPR file (not only the absence of a corresponding application).
At first- DPR file may be incorrectly associated (incompatible) with the installed application for its maintenance. In this case, you need to change this link yourself. For this purpose, right-click on the DPR file you want to edit, click on the option "To open with" and then select the program you have installed from the list. After such an action, the problems with opening the DPR file should completely disappear.
Secondly- the file you want to open may simply be damaged. Then, the best solution is to find a new version, or download it again from the same source as before (maybe for some reason in the previous session the download of the DPR file has not been completed and it cannot be opened properly).

If you have a computer installed antivirus software can scan all files on the computer, as well as each file separately... You can scan any file by right-clicking on the file and selecting the appropriate option to scan the file for viruses.

For example, in this figure, file my-file.dpr, then you need to right-click on this file, and select the option from the file menu "Scan with AVG"... Selecting this option will open AVG Antivirus, which will scan this file for viruses.


Sometimes an error can result from incorrect software installation, which may be due to a problem encountered during the installation process. It may interfere with your operating system associate your DPR file with the correct application software influencing the so-called "File extension associations".

Sometimes simple reinstalling MacroMates TextMate might solve your problem by correctly linking DPR with MacroMates TextMate. In other cases, problems with file associations can result from poor software programming developer and you may need to contact the developer for further assistance.


Advice: Try updating MacroMates TextMate to the latest version to make sure the latest patches and updates are installed.


It may seem too obvious, but often the DPR file itself may be causing the problem... If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (for example, a power outage or other reason), the file may be damaged... If possible, try getting a fresh copy of the DPR file and try opening it again.


Carefully: A damaged file can cause collateral damage to previous or pre-existing malware on your PC, so it is very important that you have an updated antivirus running on your PC at all times.


If your DPR file related to the hardware on your computer to open the file you may need update device drivers related to this equipment.

This problem usually associated with types of media files that depend on the successful opening of the hardware inside the computer, for example, sound card or video card... For example, if you are trying to open an audio file but cannot open it, you may need to update sound card drivers.


Advice: If, when you try to open your DPR file, you get SYS file related error message, the problem could probably be related to damaged or outdated device drivers that need to be updated. This process can be facilitated by using a driver update software such as DriverDoc.


If the steps did not solve the problem and you're still having problems opening DPR files, it could be due to lack of available system resources... Some versions of DPR files may require a significant amount of resources (e.g. memory / RAM, processing power) to open properly on your computer. This problem occurs quite often if you are using fairly old computer hardware and at the same time a much newer operating system.

This issue can occur when the computer has a hard time completing a task, as the operating system (and other services running in the background) can consume too many resources to open DPR file... Try closing all applications on your PC before opening Pascal Source Code. By freeing up all the available resources on your computer, you will provide a better environment for trying to open the DPR file.


If you completed all the steps above and your DPR file still won't open, you may need to run equipment upgrade... In most cases, even with older hardware versions, the processing power may still be more than adequate for most custom applications (unless you're doing a lot of CPU-intensive work like 3D rendering, financial / scientific modeling, or heavy multimedia work) ... Thus, it is likely that your computer does not have enough memory(more commonly called "RAM", or random access memory) to perform the task of opening a file.


.CAB file format

This is the file format that Delphi now offers to its users for posting on the Internet. The Cabinet format is an effective way to package multiple files. The cabinet format has two key characteristics: multiple files can be stored in a separate cabinet (.cab file), and data compression is performed depending on the file type, which significantly increases the compression ratio. The creation of a Cabinet file also depends on the number of files to be packed and the type of access expected to them (sequential, random, simultaneous access to all files, or access to several files at the same time). Delphi does not take advantage of file type compression.

.LIC file format

In reality, the .lic file format does not exist as such. Usually these are the same text files containing one or two key lines.

.INF file format

All inf files are composed of sections and items. Each named section contains corresponding items. All inf files start with a header section. After the heading, the included sections can appear in any order. Each title is a line with [Title Name]. Items follow: ItemA = ItemDetail. For more information, refer to the Device Information File Reference.

.Dpr file format

The dpr file is the central file for a delphi project. It is the first entry point for the program. dpr contains links to other files in the project and links forms to the corresponding modules. This file should be edited with extreme caution, as inept actions can lead to the fact that you will not be able to load your project. This file is critical when loading and moving (copying) a project.

.Pas file format

This is a standard text file that can be edited with a text editor. This file needs to be edited with some caution as it may end up losing some of the benefits of the other two tools. For example, adding code for a button with a type declaration will not affect the corresponding .dfm file of the form in any way. All pas files are critical when rebuilding the project.

.Dfm file format

This file contains a description of the objects located on the form. The contents of the file can be seen as text by right-clicking the context menu and selecting the "view as text" item, or by using the convert.exe converter (located in the bin directory), which also allows you to convert the file to text form and vice versa. This file needs to be edited very carefully as it may end up in the IDE not being able to load the form. This file is critical when moving and rebuilding a project.

Format. DOF files

This text file contains the current settings for project options such as compiler and linker settings, directories, conditional directives, and command line parameters. These settings can be changed by the user by changing the project settings.

.DSK file format

This text file stores information regarding the state of your project, such as the open window and its coordinates. Like a. DOF file, this file is created based on the current environment of the project.

.DPK file format

This file contains the source code of the package (similar to the .DPR file of the standard Delphi project). Like a .DPR file, a .DPK file is also a simple text file that you can edit (see warning above) with a standard editor. One of the reasons you can do this is by using the command line compiler.

.Dcp file format

This binary image file actually consists of an actual compiled package. The complete information on symbols and additional headers required by the IDE is contained in the .dcp file. To build a project, the IDE must have access to this file.

.DPL file format

It is actually an executable runtime package. This file is a Windows DLL with integrated Delphi-specific features. This file is required when deploying an application that uses packages.

DCI file format

This file contains both standard and user-defined code templates used in the IDE. The file can be edited with a standard text editor, or in the IDE itself. As with any text data file used by Delphi, it is not recommended to edit it yourself.

DCT file format

This is a "private" binary file that contains information about user-defined component templates. This file cannot be edited in any way through the IDE. Since this file is a "personal" IDE file, compatibility with later versions of Delphi is not guaranteed.

.TLB file format

The TLB file is a "private" type library binary. Provides information to identify the types of objects and interfaces available in an ActiveX server. Like a module or header file, the .TLB serves as a repository for the required symbolic information for the application. Since this file is "personal", compatibility with future versions of Delphi is not guaranteed.

DRO file format

This text file contains information about object storage. Each item in this file contains specific information about each available item in the object store. Although this file is a simple text file, we strongly advise against editing it manually. The repository can only be edited using the Tools | Repository menu in the IDE itself.

.RES file format

This is a standard windows binary format resource file that includes application information. By default, Delphi creates a new .RES file each time a project is compiled into an executable application.

DB file format

Files with this extension are Paradox standard files.

DBF file format

Files with this extension are standard dBASE files.

Gdb file format

Files with this extension are standard Interbase files.

.DMT file format

This "private" binary contains built-in and user-defined menu templates. This file cannot be edited in any way through the IDE. Since this file is "personal", compatibility with future versions of Delphi is not guaranteed.

DBI file format

This text file contains the information required to initialize the Database Explorer. This file cannot be edited in any way through the Database Explorer.

DEM file format

This text file contains some standard country-specific formats of the TMaskEdit component. As with any text data file used by Delphi, it is not recommended to edit it yourself.

.OCX file format

An OCX file is a specialized DLL that contains all or more of the functionality associated with an ActiveX control. The OCX file was conceived as a "wrapper" that would contain the object itself and a means to communicate with other objects and servers.

- The extension (format) is the characters at the end of the file after the last point.
- The computer determines the type of file precisely by the extension.
- By default Windows does not show file name extensions.
- Some characters cannot be used in the file name and extension.
- Not all formats are related to the same program.
- Below are all programs with which you can open the DPR file.
