# FolderCantHaveRegexToCrawl

A regular expression to restrict the folders that are processed.

Folders with paths that match the regular expression are not processed, and everything inside those folders is excluded.

Because subfolders of folders excluded by this parameter do not need to be processed at all, using this parameter to exclude parts of folder trees can be more efficient than using `FolderCantHaveRegex`.

Type: | Regular Expression
Default: |
Required: | No
Configuration Section: | TaskName or FetchTasks or Default
Example: |
    FolderCantHaveRegexToCrawl=^//Top of Information Store/Inbox/Folder
The messages inside `Folder` and its subfolders are not retrieved.
