MacOS X 10.4.8 RB 2007R1 I let the user select a folder, then I search through the items in that folder looking for jpeg files. Right now I am looking at the extension to determine if it is a jpeg or not. But I am trying to determine if a file without an extension is a jpeg file. If I take a jpeg file with an extension, and use the MacOS System "Get Info" to delete the extension, the System "Get Info" still displays the "Kind" as a jpeg file. But I cannot figure how to determine this from within RealBasic. When I look at the contents of the folderitem, for the file without the jpeg extension, in debug mode, there is nothing there to indicate the file type/kind. Any suggestions?
From looking at a handful of JPEG files in a hex editor, it appears that the
first 10 bytes of every JPEG file is identical: ff d8 ff e0 00 10 4a 46 49 46. So you might consider opening each file, or each questionable file perhaps, and reading the first 10 bytes of its binarystream to see if it matches that pattern. _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives of this list here: <http://support.realsoftware.com/listarchives/lists.html>
