File Extension PTB
File extension PTB is an abbreviation of PubTech BatchWorks script. Scripts of this type are made using a scripting language. These programming languages are written to control a software application. This could be software that directly employs computer capabilities. Scripts are usually treated by the operating system as distinct and different from software programs executed by the processor.

Their source code is viewed as a separate executable application, which executes independently from any other application. PTB file scripts are also distinct in their core code from the application from which they are running. The application and the script will be written in dissimilar languages and become accessible to the end user who has the ability to adapt and change the application according to his or her needs. These scripts often, but not always, are interpreted from their source codes.

This is different from the applications they are associated with which traditionally translate text into computer or source language for the native machine or system from where they are supposed to run. Generally, file extension PTB are embedded or their code is placed inside the application code with which they have an association. These batch files are actually text files that contain commands to be executed by the associated application that acts as the command interpreter. When they are run, the 'shell' application reads the file and executes the commands inside the batch file in a line-by-line mode.

PTB file extension become very important in running automated encoded instructions. System administrators use these files to automate repetitive tedious processes without user intervention. With the coming of Windows Operating System and its GUI interface, running of these scripts can be done without a command line interface. Thus, these scripts have been coded to interact with the graphical Windows, buttons and menus that are found in GUI generated systems.

File extension PTB are also useful when one wants to configure a standard state. As a result, they can also be used to control an application running in GUI mode. This has enabled the creation of what are called macros that work through mouse clicks or simulated key presses. This has made it easy to write computer viruses commonly called macro viruses that exploit this capability. Macro viruses can access and execute when documents are opened creating very risky situations.
