Not every file in your project needs tracking by Git. Examples of files that typically don't need tracking include temporary files from your development environment, test outputs, and logs.
You can use several mechanisms to inform Git which files in your project shouldn't be tracked and to ensure that Git doesn't report changes to those files. For files that Git doesn't track, you can use a .gitignore or exclude file. For files that Git already tracks, you can instruct Git to stop tracking them and ignore any changes.
[!INCLUDE azure-repos-prerequisites]
You can tell Git not to track certain files in your project by adding and configuring a .gitignore file. Review the following key points:
- Untracked files: Entries in a
.gitignorefile apply only to untracked files. They don't prevent Git from reporting changes to tracked files. Tracked files are files that were committed and exist in the last Git snapshot. - File search patterns: Each line in a
.gitignorefile specifies a file search pattern relative to the.gitignorefile path. The .gitignore syntax is flexible and supports the use of wildcards to specify individual or multiple files by name, extension, and path. Git matches.gitignoresearch patterns to the files in your project to determine which files to ignore. - Location: Typically, you add a
.gitignorefile to the root folder of your project. However, you can add a.gitignorefile to any project folder to let Git know which files to ignore within that folder and its subfolders at any nested depth. For multiple.gitignorefiles, the file search patterns that a.gitignorefile specifies within a folder take precedence over the patterns that a.gitignorefile specifies within a parent folder. - Creation: You can manually create a
.gitignorefile and add file pattern entries to it. Or you can save time by downloading a.gitignoretemplate for your development environment from the GitHub gitignore repo. - Benefits: One of the benefits of using a
.gitignorefile is that you can commit changes and share it with others.
Note
Visual Studio automatically creates a .gitignore file for the Visual Studio development environment when you create a Git repo.
Visual Studio 2022 provides a Git version control experience through the Git menu, Git Changes, and shortcut menus in Solution Explorer. Visual Studio 2019 version 16.8 also offers the Team Explorer Git user interface. For more information, see the Visual Studio 2019 - Team Explorer tab.

Visual Studio 2019 version 16.8 and later versions provide a Git version control experience while maintaining the Team Explorer Git user interface. Follow these steps to use Team Explorer:
- Go to the menu bar and select Tools > Options > Preview Features.
- Clear the New Git user experience checkbox to enable Team Explorer.
You can use Git features from either interface interchangeably.
To ignore files using Team Explorer:
- In the Changes view of Team Explorer, right-click any changed file that you want Git to ignore.
- Select Ignore this local item or Ignore this extension. These menu options don't exist for tracked files.

- The Ignore this local item option adds a new entry to the
.gitignorefile and removes the selected file from the list of changed files. - The Ignore this extension option adds a new entry to the
.gitignorefile and removes all files with the same extension as the selected file from the list of changed files.
Either option creates a .gitignore file if it doesn't already exist in the root folder of your repo and adds an entry to it.
Each entry in the .gitignore file is either: a file search pattern that specifies which files to ignore, a comment that begins with a number sign (#), or a blank line (for readability). The .gitignore syntax is flexible and supports the use of wildcards to specify individual or multiple files by name, extension, and path. All paths for file search patterns are relative to the .gitignore file.
Here are some examples of common file search patterns:
# Ignore all files with the specified name.
# Scope is all repo folders.
config.json
# Ignore all files with the specified extension.
# Scope is all repo folders.
*.json
# Add an exception to prevent ignoring a file with the specified name.
# Scope is all repo folders.
!package.json
# Ignore a file with the specified name.
# Scoped to the 'logs' subfolder.
/logs/test.logfile
# Ignore all files with the specified name.
# Scoped to the 'logs' subfolder and all folders beneath it.
/logs/**/test.logfile
# Ignore all files in the 'logs' subfolder.
/logs/As soon as you modify a .gitignore file, Git updates the list of files that it ignores.
Note
Windows users must use a slash (/) as a path separator in a .gitignore file, instead of using a backslash (\). All users must add a trailing slash when specifying a folder.
You can designate a .gitignore file as a global ignore file that applies to all local Git repos. To do so, use the git config command as follows:
git config core.excludesfile <gitignore file path>A global .gitignore file helps ensure that Git doesn't commit certain file types, such as compiled binaries, in any local repo. File search patterns in a repo-specific .gitignore file have precedence over patterns in a global .gitignore file.
You can also add entries for file search patterns to the exclude file in the .git/info/ folder of your local repo. The exclude file lets Git know which untracked files to ignore. It uses the same syntax for file search patterns as a .gitignore file.
Entries in an exclude file apply only to untracked files. They don't prevent Git from reporting changes to committed files that it already tracks. Only one exclude file exists per repo.
Because Git doesn't commit or push the exclude file, you can safely use it to ignore files on your local system without affecting anyone else.
Sometimes it's convenient to temporarily stop tracking a local repo file and have Git ignore changes to the file. For example, you might want to customize a settings file for your development environment without the risk of committing your changes. To do so, you can run the git update-index command with the skip-worktree flag:
git update-index --skip-worktree <file path>To resume tracking, run the git update-index command with the --no-skip-worktree flag.
Or, you can temporarily stop tracking a file and have Git ignore changes to the file by using the git update-index command with the assume-unchanged flag. This option is less effective than the skip-worktree flag, because a Git pull operation that changes file content can revert the assume-unchanged flag.
git update-index --assume-unchanged <file path>To resume tracking, run the git update-index command with the --no-assume-unchanged flag.
Entries in a .gitignore or exclude file have no effect on files that Git already tracks. Git tracks files that you previously committed. To permanently remove a file from the Git snapshot so that Git no longer tracks it, but without deleting it from the file system, run the following commands:
git rm --cached <file path>
git commit <some message>Then, use a .gitignore or exclude file entry to prevent Git from reporting changes to the file.
