From a coding point of view the following applies:
(1) When an end user attempts to open up a file, the open file dialogue box may limit the selection to those of an allowable format. All this does it check the extension of the file. To get around this, just chose the 'select all' option under the extension setting. If this is not available, then you need to chaneg the extension type.
(2) The application coding may be set up to reject files that don't fit within a certain array of extensions. Not often done, but sometimes codes want to stop people from importing a file they don't want you to! Again, chamging the extensions allows you to import, but that's not to say it will work.
