[ckan-dev] File size

Fri Nov 6 07:47:28 UTC 2015

I have written an extension that updates the filename, size, MIME type and calculates various checksums (MD5, SHA1-512)

Ill see about popping it online in the next couple of days.

Regards Tim

For uploaded files, you can find the file path on the server side and return the file size from the file system as a template helper.

eg.
