Project files not visible: directories/files hidden in project explorer

Problem

Certain files or directories are not visible in the project explorer. Attempting to rename a directory to a certain name results in a warning: “Trying to create a directory with ignored name, result will not be visible.” Files inside such a directory cannot be navigated.

Resolution

1. In the project explorer, click the three dots (…), navigate to Appearance, and check Excluded files to show excluded items in the project view.
2. If the item remains hidden, verify the exclusion/ignored file settings:
   • Open File | Settings | Directories.
   • Ensure the item is not marked as “Excluded”.
   • Open File | Settings | Editor | File Types, Ignored files and folders tab
   • Ensure the folder/file name isn't in the list of ignored file patterns
3. For further details about managing ignored file patterns, refer to Configuring files to ignore in the IDE.
