Is it safe to delete some folders and files inside the folder 'files'?
I have just updated my website to C5's last version and all it's ok.
But I have got only 500 Mb of hosting, and I having some space problems now.
The size of each folder is:
concrete 32 700 KB
config 12.0 KB
files 200 656 KB
jobs 4.00 KB
languages 184 KB
packages 880 KB
updates 40 568 KB
There is a lot of subfolders and files in the "files" main folder. The date of most of them is one o more years ago. And there is a "tmp" folder, sized 164 Mb, with some .zip files inside.
Would it be safe to delete his content?
