you are getting unsupported format because a .lnk file is not a supported file format so the iXpand drive app does not know how to open it. I am curious though how did this file get created? a .lnk file is a link file which typically is used like a shortcut to open a file or location when it is actually stored in a different location. the iXpand drive app should not have been able to create this file so it must have happened somewhere else.
If the .lnk file is pointing to the data when you use it on your computer I would suggest connecting the drive to the computer backup all the data then erase, format, or delete the .lnk file from the iXpand drive . If formatting use FAT32 or exFAT as the file system. Once that is done copy the data back to the drive. Do not copy any .lnk files to the drive. Once all the data is on the drive retry it with the iXpand drive app and you should be able to see the data.
