If you have files that you do not want to be recognized by the IDE, you can configure the IDE to ignore these files.
To specify files to be ignored:
The following are some useful characters for regular expressions.
| Character | Description |
|---|---|
| | | Or. |
| ^ | Matches all file or directory names beginning with the subsequent characters. |
| $ | Matches all file or directory names ending with the preceding characters. |
| \ | Escape character. Necessary if you want to match to a period (.) or other special character. |
| .* | Wildcard. |
For example, if you want to ignore all files with the .bak extension, type \.bak$ in the Ignored Files property.
