Thank you for reply, but the thing is that the information about lack of free space hasn`t been changed for a long time (a week or so) despite the fact that I'd deleted a few Gb. My calculations say that I have about 8 Gb in my account, at the same time I cannot upload any file because of lack of free space. Deleting files dosn`t help.

Thank you

The issue remains unsolved
