Folder seen as file when connected as MTP I have Redmi 1S phone running Andriod 4.3 (MIUI v56).  When connected to a PC (Windows 7 32Bit) in MTP mode, one of the folders named Backup (present in internal memory) is seen as a file and effectively inaccessible. 

When connected through FTP, that folder is seen and accessible through an FTP client (can be downloaded as well to PC). Folder is accessible from within the File Manager app on phone as well. 

I am clueless what is selectively causing this single folder being seen as a file when the device is connected in MTP mode! Any support to solve this would be great. Thanks.
Because of the different way files and folders are handled on Windows when compared to other operating systems, it could be that the folder is corrupted and Windows is seeing it as a file (which it really is in the Android filesystem).  It may be possible to fix this problem by:


Creating a new folder,
Moving the contents of Backup into the new folder,
Removing Backup, and finally
Renaming the new folder to Backup


However, depending on what the underlying problem truly is, this may not fix it.
