Simple access to a file’s extension has been requested - a new optional column has been added to the various library views - it shows the extension of the ‘primary file’ for a multi-file download, expand the files to see the individual extensions if required.
The ability to see an individual file’s CRC and MD5 hash values has been requested by this idea. You will need to be in advanced mode to see these columns in the column-setup wizard. The hashes are calculated on demand, not automatically. Hash calculation can take quite a bit of CPU and file IO, you probably don’t want this automatically kicking in while using ‘play now’ to watch something… To calculate the hashes for multiple files in one go multi-select the files (or CTRL+A) and then right-click and select the ‘calculate hash’ option.
