Technical
Masks are case-insensitive, since the Windows platform does not support case-sensitive file names
(yes, you can have mixed case in a file name but that's visual fluff - the OSitself does not care).
Mask Format
Here are the different mask formats available:
l Literal characters:Any alphanumerical character is considered literal character and must appear. For
example, a mask of "trigger.txt"will not capture any other files than that name.
l Wildcards:Two wildcards are available in masks.
l Asterisk (*):Supports any number of characters. *.txt would pick up any text file, file*.txt would
pick up any file starting with file and any characters:file1.txt, filetest.txt.
l Question Mark (?):Supports a single character. file?.txt would pick up File1.txt or filea.txt , but
not file13.txt or filetest.txt.
l Brackets:Specifies a set of supported characters, or range of characters. Only one character from the
range is accepted, making this a subset of the ? wildcard.
l Sets:[13ab] defines support for one of these 4 characters. file[13ab].txt would pick up file1.txt ,
filea.txt , but not file13.txt or filea3.txt.
l Negative Sets:[!13ab] indicates the character should NOTbe part of the set. file[!13ab].txt
would pick up file2.txt and filec.txt but not file1.txt or fileb.txt (nor would it pick up file13.txt or
filea3.txt).
l Ranges:[1-5] , [a-d] define ranges between the characters. file[1-5].txt would pick up file1.txt
and file4.txt but not file6.txt or file13.txt.
l Negative Ranges:Negative ranges such as [!2-4] are also possible.
Technical
Filename containing brackets can be a hassle when attempting to capture them with a mask and
using sets or ranges. You can capture a set that contains an opening bracket ([[] ) , but not a closing
bracket as the closing bracket always ends the set or range. There is no escape character available in
masks.
