Buggy DirectoryFindFiles() (used by BrowseTXT/XMLFiles) removed and replaced with TSongs.FindFilesByExtension()
- DirectoryFindFiles() was not applicable as: - it found files that contained the extension anywhere in the file, e.g. file.txt.bak - was not recursive (caller had to explore subdirs himself) - was not correct if ReturnAllSubDirs=false, as it also returned matching directories with IsFile=true and IsDirectory=false git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/branches/experimental@1912 b956fd51-792f-4845-bead-9b4dfca2ff2c
