You can exclude specific files, folders, and file types from deliveries, for example:
backup files
built artifacts
To exclude items you define ignore rules in a .dmignore file. Each location (a folder or directory) has a single .dmignore file but you can have multiple ignore files across a hierarchy of folders. You can also apply ignore rules recursively, for example, you can ignore all *.tmp files in the current folder and all child folders.
NOTE
Rules are case insensitive on Windows and case sensitive on Linux.
You can use the following wildcards:
Asterisk (*): represents one or more characters.
Question mark (?): represents one character.
In wizards where you deliver changes you can optionally disable ignore rules. For example, you may want to deliver all files, including those that you do not normally need to control.
To edit .dmignore files in a language that corresponds to your locale, on your machine check the language settings for non-Unicode programs.
Ignore rules are not the same as the include and exclude local files filters in the Merge, Synchronize, and Deliver wizards.
