The Icon attribute will allow us to specify the Id of an Icon tag specified somewhere else in the source rather than the actual filename even if the. Description of other folders might come later in the source code. Shortcuts can be non-advertised a simple link pointing to the file in the shortcut's Properties dialog or advertised with the link greyed out. This second form lets Windows Installer repair the installation by replacing any missing file the shortcut points to.
As you might expect, for an application with hundreds or even thousands of files, this will mean hundreds or thousands of components. Yes, this is normal, this is the expected way to do it. Don't be afraid, there will be no performance problems, the Windows Installer is prepared to handle this all right.
Typing all those hundreds or thousands of components into the WiX source file presents another challenge, of course. The toolset has a small utility that can help with this more about it later but the real solution is a conceptual change. Stop considering the setup program as a separate application that has to be written in a rush when the main application is already finished. As the WiX source files and the toolset itself can be integrated into your development environment easily, you should keep them in sync all the time.
As soon as you start working on a new module or add a new registry reference to your program, modify the corresponding WiX source file at the same time. This way, the setup will be finished together with the application itself and there will be no need to extract all the file and other pieces of information required for the installation later.
As the WiX project can be modularized more about this later , this approach works just as well if you have a large team working on the application rather than a single developer.
And now, the closing tags for the directory elementsone less than what we started with because we're not yet finished. Only then will the outermost Directory tag be closed.
As we need to remove the program folder when the product is uninstalled, we need to create a fourth component as well. The RemoveFolder tag will describe our intention; the On attribute will determine when the folder will be removed possible values are install , uninstall , and both. As already mentioned, all components must have their own key path. In this case, this will be an extra RegistryValue tag. This tag is beyond the scope of this first lesson, we will return to it later.
Putting the KeyPath attribute on the component or the folder might work, too, but that would result in a linker warning. So, please, accept this solution for now as something temporarily unexplained for the sake of avoiding any messages from the compiler and linker.

For example, the Word document looks like a file with a W in the corner, while an Excel spreadsheet looks like a file with an X in the corner.
And now its time to move another section of this tutorial that is how to download different types of files such as text, html, pdf, image files etc using python.
In this section, we will see how to download large files in chunks, download multiple files and download files with a progress bar. You can also download large files in chunks.
Write the following program. Now run the program, and check your download location, you will found a file has been downloaded. Now you will learn how can you download file with a progress bar. First of all you have to install tqdm module. Or a website that asks you to upload a photo might insist that it be a specific type of file.
Whatever quandary you encounter, you can usually hunt down an app that will help. Frequently, the application you used to create the file in the first place will let you save it as something else. Most of these applications let you save your pictures as a variety of file types, so you can pick the appropriate one.
Handbrake for Windows, macOS, and Linux takes video files from almost every imaginable format and converts them into any other popular video type. Beyond that, Handbrake can rip videos from DVDs and supports subtitles and chapter markers in your conversions. It can also convert a broad selection of different file types.
Think of it as a Swiss Army knife for video conversions. The application will ask you to pick a video file from the hard drive, and you can then choose the format you want to change it into. Rather than writing over the original file, VLC will create a separate copy of the newly-reformatted video.
