How to uncompress a file that has been compressed in Windows to save space (note that this is different to a zip file):

Note the indicator on the file that shows its compressed (see 1 below)


To uncompress the file select it then right-click and properties (see 2 below)


IN the properties dialog box chick advanced (see 3 below) then untick the "Compress contents to save space" checkbox (see 4 below), click OK then OK again to close the dialog boxes.


Note that the indicator is now gone from the file (see 5 below)


PS. Its a bad idea in the first place, don't use this feature
