Hello,

my extrenal hard drive has a capacity of 300 GB, when i check its properties i see that it as a used 220 GB has been used. but when you check its folders I can only see few files which sums up to 70 GB. I cant see the other files.

Use tune up utilities and it shows all the files in the disc according to the size of the file
