DUP0 File

Did your computer fail to open a DUP0 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .DUP0 files.

What is a DUP0 file?

The .dup0 file extension is one of the three file extensions used in Samsung smart phones to serve like a thumbnail file. Thumbnail files are created on a phone so that when the files are loading, especially the ones with large memory, will not lag or hang- up. DUP0 is not a thumbnail per se, but works like one.

The .dup0 file extension will appear when the device is synched using the Samsung Kies software. Samsung Kies is a computer application similar to iTunes for iOS devices that it manages the transfer of files from one device to the other or computer and vice versa. DUP0 means duplicate0. The number 0 represents that the original file being duplicated is a music or audio file. Duplicate files are used to ease out the transfer of files and to 'smooth the lines in the wire'. After the transfer, you can always remove the DUP0 files without causing problems on the device.
