Filename$ = OpenFileRequester(Title$, DefaultFile$, Pattern$, PatternPosition [, Flags])Description
Opens the standard requester for the user to choose a file. The title can be specified to replace the default one. The DefaultFile$ is useful to initialize the requester in the right directory and with the right filename.
Title$ The title of the requester window. DefaultFile$ The default file displayed when the requester is opened. Pattern$ A standard filter which allow to display only the files which end with such or such extension. It has to be in the following form : "Text file | *.txt | Music file | *.mus;*.mod" The pattern always works in pairs: name (which really appears in the filter) and extension (ie: *.txt). Several extensions can be specified for a single type by using the ; (semi-colon) separator (not supported on OSX, the requester always displays all files). PatternPosition Specifies which pattern must be the default. It begins from 0 up to the number of pattern minus 1 (because the index for the first pattern begins at 0). Once the requester has been closed, SelectedFilePattern() can be used to get back the selected pattern (not supported on OSX). Flags (optional) It can be a one of the following values:#PB_Requester_MultiSelection: Enable the multiselection. (see NextSelectedFilename())
The selected filename, or an empty string if the requester has been canceled by the user.
The returned 'Filename$' can be easily split into file, path and extension string with the following functions: GetFilePart(), GetPathPart() and GetExtensionPart().
