I want to download all *.txt files from a WebDAV share. Is there a request/methode to get a list of files from this folder?
I´m new to WebDAV and at the w3.org WebDA
The link you pointed at is not the WebDAV specfication, but the HTTP specification. If you want to list the contents of a directory (collection) you must use the PROPFIND method instead, which should return an XML document with all the information.
