XCP exclusion

For example, if snapshot is set for the share of \\ svm01 \ smb02, the \\ svm01 \ smb02 \ ~ snapshot folder will be displayed for FAS. (When show snapshot is set)
-exclude path (‘* \ ~ snapshot \ *’) was able to exclude at scan time.
I wanted to exclude the regular folder \\ svm01 \ smb02 \ test, but I didn't exclude it without -exclude path (‘* \\ test \\ *’).(Two \)
It seems that some folders can be excluded with -exclude path (‘* \ <$ name> \ *’), but what is the condition for having to add two \s?
Or is it better to always have two \s attached?
