Masks
A file name that includes characters meant to be replaced at run-time is referred to as a mask.
Masks can be used in many edit boxes and can be used, for instance, to select multiple files.
File selection is typically limited by fixed characters or special wildcard characters. If you create
a Folder Capture Input task and enter *.* in the Masks box, the Input task will grab all the files
that are put in the source folder. If you enter *.mdb instead, the task will only take those
database files that have an mdb extension. You can use any standard wildcard character in
PlanetPress Workflow.
Note
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).
Tip
You can specify multiple masks in one edit box if you separate them with a semicolon (;).
For example: *.xml;*.pdf.
Mask Format
Here are the different mask formats available.
l
Literal characters: Any alphanumerical character is considered a 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.
