Canto will recognize if an uploaded file is a duplicate of a preexisting file in the system. Canto uses the MD5 technology, which is like a digital fingerprint for each file. So, unless the content is modified the MD5 hash tends to be the same and Canto will flag that as a duplicate.
Administrators can set up options for how to deal with duplicates.
1) Navigate to Settings, and then select the Configuration Options tab, followed by the Duplicates sub-tab.
From here, Administrators can either enable or disable automatic duplicate check by checking the box.
When enabled, the options for handling duplicates are:
- be notified if the uploaded file is a duplicate (‘Show dialog’)
- the duplicate file is immediately removed (‘Remove duplicates without dialog’)
An option to immediately remove duplicates from storage services (Box, Dropbox and Google Drive) is also available.
