Showing this error msg

IndexError                                Traceback (most recent call last)
<ipython-input-5-9cd613c11ac6> in <module>()
      4 
      5 filename= os.listdir('/content/Real-ESRGAN/results')
----> 6 files.download('/content/Real-ESRGAN/results/'+filename[0])

IndexError: list index out of range

Answer 1

What is likely happening is that your filename list is empty. Thus, it has no element at index 0, so your index is out of range.

Answer 2

this code works perfectly:

for i in os.listdir('/content/youfolder') :    
#print(i) 
files.download('/content/youfolder/'+i)
