This screen allows you to create/view/edit a File Name Format.

These are used to format the names of documents generated from a Document Template.

The fields are as follows:

• Name - the format name
• Description - a description of the format
• Expression - the xpath expression to format file names

The expression is provided with:

• a $file variable. This represents the file name of the original template, minus the extension
• the object that the template is being applied to e.g. act.customerAccountChargesInvoice, act.customerAccountPayment, act.patientDocumentLetter, act.customerDocumentForm, act.supplierDocumentAttachment
• a $patient variable, if a patient is linked to the act
• a $customer variable, if a customer is linked to the act, or the owner of the patient, if a there is only a patient present
• a $supplier variable, if a supplier is linked to the act

To ensure that generated file names are valid, any illegal characters such as \, /, :, *, ?, <, >, and | are replaced with underscores.
