Guidelines for exclusion filters

Review the following guidelines for exclusion filters.

Using wildcards

Supported wildcards include an asterisk (*) to represent zero or more characters and a question mark (?) to represent zero or one character.

NOTE Be careful when using the wildcard *. Depending on the wildcard location, you can match folders whose name matches the filter pattern and their contents, even when the names of those files do not match the filter. For example, *\\log*.txt also excludes files with the .txt extension in a folder whose name starts with log, even if the names of the files do not start with log.

Excluding by file type

The File Type filter enables you to exclude files and folders based on file extension.

You can specify a single extension or multiple file extensions. Separate multiple entries with a comma and do not add a space between entries. You can also specify related extensions by using wildcards. For example, *.doc? matches both .doc files and .docx files.

Excluding by type and path

You can combine extension and path to exclude all files of a particular type without respect to the file location.

For example *\\log*.txt matches all text files (.txt) where the file name starts with log, at any path.

You can also exclude all files of a particular type from a specific path. For example, C:\\abc\\*.txt matches all text files in the folder C:\abc. All matching files under subfolders of that specific path are recursively excluded.

You can combine these guidelines to exclude all files that match a specific name pattern under a particular path. For example, C:\\folder\\log*.txt.

Excluding by file path

The Path filter enables you to exclude files and folders in a specific path.

You can specify an absolute or relative path.

The following table provides examples for excluding files and folders using absolute and relative paths.

Table 1. Absolute and relative path examples
Type of path	Folder	File
Absolute	F:\\folder1\\folder2\\* In this example, the filter excludes all files and folders under F:\folder1\folder2.	F:\\folder1\\folder2\\sample.txt In this example, the filter excludes the sample.txt file under F:\folder1\folder2.
Relative	\\folder1\\folder2\\	*\\folder1\\folder2\\sample.log
	In this example, the filter excludes all files and folders under any volume with the hierarchy folder1\folder2.	In this example, the filter excludes all sample.log files under any volume with the hierarchy folder1\folder2.
	D:\\\\folder1\folder2\\	D:\\*\\folder1\folder2\\sample.log
	In this example, the filter excludes all files and folders under any folder in D: with the hierarchy folder1\folder2.	In this example, the filter excludes all sample.log files under any folder in D: with the hierarchy folder1\folder2.
