What is PYW file?

The file with the extension PYW is the Developer Files file type. In addition to this file, the Developer Files category includes 1205 related files. Python GUI Source Format is supported by 4 operating systems. These systems consist of , Linux, Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. There are also 3 alternative programs to handle the PYW file. The Sublime Text, Python programs will also handle the file when the pythonw program does not fulfill its role.

How to open PYW file?

The most common problem when using Python GUI Source Format is that a specific PYW is not associated with the program. This causes the file PYW to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the PYW file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install pythonw

The first step is to check if the computer has the pythonw program installed. This can be achieved by typing pythonw into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file PYW with pythonw. Below is a list of programs that support the file PYW.

Programs to open PYW file

Remember to download programs supporting PYW files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of pythonw with PYW files

If, despite the installed application, the PYW file does not start in the pythonw application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the pythonw application as the default for handling the PYW file.

Step 3. Update pythonw to the latest version

If, despite the association of the pythonw program with the Python GUI Source Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the PYW file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The PYW file may be unusually small compared to the original file. This is most often caused by a problem while downloading the PYW file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our PYW file. Sometimes virus-infected PYW files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the PYW files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged PYW files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file PYW except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move PYW to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the PYW file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
