bug: FileAlreadyExistsError

[aviadr1]

if the last file (i.e. fileName+"."+str(i+1)) already exists, os.rename will not overwrite it (at least not on windows machines)

RotatingTextFile/RotatingTextFile/__init__.py

Line 37 in a82d2f7

os.rename(self.fileName+"."+str(i),self.fileName+"."+str(i+1))

therefore it is advisable to delete the last file before rotation

[aviadr1]

from the python docs
os.rename(src, dst, *, src_dir_fd=None, dst_dir_fd=None)
...

On Windows, if dst exists a FileExistsError is always raised.
...

If you want cross-platform overwriting of the destination, use replace().
