PDE File Extension

What is PDE file?

PDE file contains a source code of application written in Processing programming language. PDE files are by default saved in separate folder along with other files used by given application (for example, image files).

Processing programming language

Released in 2001, Processing language was designed with the purpose of teaching fundamentals of computer programming to persons with no programming background. It is implemented in Java. Processing is known for its attractive interface and visual presentation of code and processes. Processing is an ideal tool for visual programming. Processing is distributed under open-source license.

Programs which support PDE file extension

The list that follows enumerates programs compatible with PDE files, divided into 3 categories based on operating system on which they are available. Files with PDE extension, just like any other file formats, can be found on any operating system. The files in question may be transferred to other devices, be it mobile or stationary, yet not all systems may be capable of properly handling such files.

How to open file with PDE extension?

Being unable to open files with PDE extension can be have various origins. What is important, all common issues related to files with PDE extension can be resolved by the users themselves. The process is quick and doesn’t involve an IT expert. We have prepared a listing of which will help you resolve your problems with PDE files.

Step 1. Download and install Processing

The main and most frequent cause precluding users form opening PDE files is that no program that can handle PDE files is installed on user’s system. The solution is straightforward, just download and install Processing. The full list of programs grouped by operating systems can be found above. One of the most risk-free method of downloading software is using links provided by official distributors. Visit Processing website and download the installer.

Step 2. Update Processing to the latest version

If you already have Processing installed on your systems and PDE files are still not opened properly, check if you have the latest version of the software. Software developers may implement support for more modern file formats in updated versions of their products. This can be one of the causes why PDE files are not compatible with Processing. The latest version of Processing should support all file formats that where compatible with older versions of the software.

Step 3. Associate Processing Development Environment Source Code Format files with Processing

If the issue has not been solved in the previous step, you should associate PDE files with latest version of Processing you have installed on your device. The next step should pose no problems. The procedure is straightforward and largely system-independent

The procedure to change the default program in Windows

• Choose the Open with entry from the file menu accessed by right-mouse clicking on the PDE file
• Click Choose another app and then select More apps option
• Finally select Look for another app on this PC, point to the folder where Processing is installed, check the Always use this app to open PDE files box and conform your selection by clicking OK button

The procedure to change the default program in Mac OS

• By clicking right mouse button on the selected PDE file open the file menu and choose Information
• Find the Open with option – click the title if its hidden
• Select Processing and click Change for all...
• Finally, a This change will be applied to all files with PDE extension message should pop-up. Click Continue button in order to confirm your choice.

Step 4. Verify that the PDE is not faulty

If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the PDE file in question. Problems with opening the file may arise due to various reasons.

1. The PDE may be infected with malware – make sure to scan it with an antivirus tool.

If the PDE is indeed infected, it is possible that the malware is blocking it from opening. It is advised to scan the system for viruses and malware as soon as possible or use an online antivirus scanner. If the PDE file is indeed infected follow the instructions below.

2. Verify that the PDE file’s structure is intact

If the PDE file was sent to you by someone else, ask this person to resend the file to you. During the copy process of the file errors may occurred rendering the file incomplete or corrupted. This could be the source of encountered problems with the file. It could happen the the download process of file with PDE extension was interrupted and the file data is defective. Download the file again from the same source.

3. Verify whether your account has administrative rights

Some files require elevated access rights to open them. Log in using an administrative account and see If this solves the problem.

4. Verify that your device fulfills the requirements to be able to open Processing

The operating systems may note enough free resources to run the application that support PDE files. Close all running programs and try opening the PDE file.

5. Verify that your operating system and drivers are up to date

Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with Processing Development Environment Source Code Format files. Outdated drivers or software may have caused the inability to use a peripheral device needed to handle PDE files.
