Файлы cab в папке temp windows 7

Периодически на машинах с Windows 7 и Windows 10 возникает следующая проблема:

Папка C:\Windows\Temp заполняется файлами вида cab_xxxx размер файлов от 0 до 2Гб и файлами вида *.log. Простое удаление файлов освободит место, но не исправит проблему. Проблема возникает из-за того, что система не может заархивировать один или несколько логов из директории C:\Windows\Logs\CBS. У машин с большим Uptime’ом размер журналов Windows>\Logs\CBS\CbsPersist_YYYYMMDDHHMMSS.log может достигать больших размеров. По какой-то причине, для архивирования этих файлов Майкрософт выбрана утилита makecab, которая не умеет работать с файлами размером более 2G.

Получается так:
335.39% – raw=2,147,450,880  compressed=133,507,765
ERROR: (FCIAddFile)Data-size or file-count exceeded CAB format limits
Неудачный запуск отставляет недописанный файл архива с первыми 2Gb.
В итоге остается временный файл cab_xxxx и каждые 30-60 минут появляется новый, что и приводит к переполнению диска.

Temporary files are common files created while running a process on Windows. However, they are of no use once the process ends. That said, CAB files temporary files, hardly removed by the user. 

While these files appear to have no impact on your PC’s performance, they do affect the storage and overall speed of the computer. This means it becomes crucial for a user to keep cleaning these files, or else it might reflect on the PC’s health.

Fortunately, some ways can enable you to delete CAB temporary files on Windows. 

In this post, let us look at these files, their importance on the PC, their impact on your system’s performance, and most importantly, how to get rid of temp CAB files on Windows.

Without further ado, let’s get started!

What are Temp CAB Files?

The CAB or cabinet files on Windows are used to store compressed system files. Entities like Windows Package Installers, Theme Packs, Device Installers, APIs, setups, etc., use this format as it allows lossless compression to maintain archive integrity with the help of embedded digital certificates. 

The OS directly uses these files, which means as a user, you never have to interact with such files. All in all, CAB files hold a library of useful files and information the operating system uses.

While these processes run in the background, there are several temporary file libraries created in the CAB format. These files are called temp CAB files and are of no use to the user or the OS after the process is over. 

Can You Delete Temp CAB Files? Where to Find CAB Temp Files?

Since every definition of CAB files defines them as a Windows operating system component, users get confused about whether to delete the temporary CAB files or not. 

If you, too, are confused, let us bust the bubble for you! YES, you can delete these temporary CAB files as they are of no use to the OS after a process is over. Sure, they do have a significant role to play when the installation process of any application is ongoing. However, these files are nothing less than a paperweight and can be easily removed when unnecessary. 

That is why, later in the post, you will find out that there are no warnings when you try to delete temp CAB files. If these were of any importance for the operating system, Microsoft would have kept them away from a regular user’s reach, just like they did with the System32 files.

Right now, you can easily find these files in the temporary directory that can be found at the following location in the Explorer – 

C:\Users\username\AppData\Local\Temp

Also, you can easily access the temporary files folder using the run command – 

%temp%

In the Run search. (Windows+R key)

While these files are useless, they sure serve as a load on the storage of your PC. Not to mention, since these files can interact with the OS, they may impact the speed and efficiency, too. Hence, getting rid of them is the best way to handle them.

5 Ways to Delete Temp CAB Files

Now that you know enough about these files, let’s look at some ways to remove them completely from your system. 

Method 1 – Find and Delete the Temp CAB Files Manually

You can go the manual route if you plan to do this regularly. It is quite simple to finish as all you have to do is –

How to Fix High CPU Usage in Windows

In the realm of operating systems, particularly Windows, efficient file management is crucial for maintaining a smooth and responsive user experience. Among the files that accumulate over time are temporary files, which Windows generates for various processes and tasks. One specific type of temporary file that users may encounter is the CAB (Cabinet) file. In this article, we will delve into what Windows Temp CAB files are, their purpose, impacts on system performance, and, most crucially, how to efficiently delete them.

Understanding CAB Files

CAB files are compressed archive files used by Microsoft Windows for storing one or more files in a single container. The main benefits of CAB files include:

• Space Efficiency: By compressing files into a single CAB file, Windows can reduce the overall disk space required for large collections of files.
