Long file names and directory entries
One last thing to keep in mind about long file names is that sometimes two directory entries aren't sufficient to store the long file name. For example, the name of the file we are working on right now is Data Recovery and Long File Names.doc. If we were saving this file to a FAT or to a FAT-32 volume, the file's DOS alias would be DATA R~1.DOC (This format might vary slightly among versions of Windows). However, the long file name is longer than what can be accommodated by the file system's 13-character limitation. As such, multiple directory entries would be created. The following list contains the entries that would actually be written to the disk's file allocation table:
DATA R~1.DOC Data Recovery and Long File Names.doc

You would only see these directory entries when viewing the disk's file allocation table through Disk Editor. If you look at the disk's directory through DOS, you might see the long file names, or you might see the DOS aliases, depending on the version of DOS. If you view the directory through Windows, you'll see the long file names. But if you use Disk Editor, you'll see something like my example above, which is how the directory entries are actually made on the disk.

In the example above, we arranged the long filename entries in a way that makes them semi-readable. In the real world though, long filename entries aren't necessarily going to be in order. In fact, they are usually listed in reverse order. They would look something like this:
Names.doc and Long File Data Recovery DATA R~1.DOC

How to recover deleted files on FAT via Data Recovery Wizard
It's easy to use Data Recovery Wizard to recover the deleting files. You just need to click "Deleted File Recovery" button. However, if the recovered files couldn't be opened, you should understand the reason why we talked about so many things about cluster. Yes, the cluster size will influence whether the recovered files could be opened/read or not. If the cluster size has been changed after you deleted the files, you should click "Complete Recovery" button. After Intelligent Searching, you should choose less than 6 file systems to build file/folder tree. And then you will see the files in exact file systems would be previewed. Once can't recover, try more times.

If you feel so slowly when you build file/folder tree, you could un-tick the "Recover RAW file" in "Option". This will speed up the process when building file/folder tree.
