Docker is a set of platform-as-a-service products that use OS-level virtualization to deliver software in packages called containers. The service has both free and premium tiers. in this short article, we shall discuss how to fix “ENOENT: No such file or directory Error in Docker build”. Please see How to stop Docker from automatically starting on Mac how to manually update Docker desktop, and how to Manage BitLocker and FileVault with Trellix Native Encryption.
The following error in the image below states that it can’t find the file in the specified directory: ENOENT: no such file or directory.
What is the AppData Folder?
Applications in Windows often store their settings and temporary data in the AppData Folder. Each Windows user account has its own AppData folder. These include application settings, files, and data unique to the applications on your Windows PC.
Before providing the answer, let us discuss some terms. The AppData folder in Windows contains user-specific preferences and profile configurations which are further divided into three subfolders.
You can access the AppData folder by pressing the Windows key + R at the same time and typing ” %appdata% ” or ” %localappdata% ” depending on whether you want to go to your Roaming folder or your Local folder.
- The roaming folder contains data that can move with the user profile from one device to the other. This means data can be synced across multiple Windows systems.
- The local folder contains data that cannot move with your user profile. This means data is not synced between multiple PCs.
- The LocalLow folder contains data that is similar to Local except it is used by applications with low integrity that run with restricted security settings. For example, Mozilla Firefox, Adobe etc.

Resolve this error message “ENOENT: no such file or directory”
Now that you have familiarized yourself with what an AppData is, then let’s proceed and resolve this issue.
This is very simple. Since each environment is unique, a good understanding of it is necessary to resolve most of your issues. Else, you will have to consume many of the resources online without success.
You can also view the AppData folder by navigating into your Users folder, which is there in the C drive. In my case, the path is C:\Users\christian.
Since Docker is unable to find the Docker folder in the local folder, we will have to copy this folder into the Roaming folder. As you can see, there is no Docker folder in it at the moment.
Now, we have successfully copied the folder to the Roaming Folder.
Start Docker again via the shortcut. It would be started without errors. As you can see, I have got an icon warning.
Note: Do not forget to update docker as is the case in my lab environment.

FAQs on Docker
You can run both Linux and Windows programs and executables in Docker containers. The Docker platform runs natively on Linux (on x86-64, ARM and many other CPU architectures) and on Windows (x86-64).
Any data that your application writes to disk gets preserved in its container until you explicitly delete the container. The file system for the container persists even after the container halts.
