I am trying to rename a file the same as a variable. The variable obviously will be string, its just so I can make my program even more automated. For example :
x = 'RenameTest'
movefile('Original.txt', '%s.txt', x)
That code doesn't work but is this possible to do?

You are amost there. The right way to do it is
x = 'RenameTest'
movefile('Original.txt', [x '.txt'])
or, if you really want to use the formatting string (not really needed)
x = 'RenameTest'
movefile('Original.txt', sprintf('%s.txt', x))

As written, just
movefile('Original.txt', [x '.txt'])
More general and where you were probably trying to head would be something like
outfile=sprintf('%s.txt',newfilebase);
movefile(oldfile,outfile)
where oldfile is a string variable containing the original name.
