Disclosed is a method to automate deletion of files on a computer network so the files can be deleted when they are no longer needed. This method includes different levels of variability so that the system administrator or file creator can determine the criteria for deletion based on length of time file has been posted and current activity for that file.

Method to Variably Automate Deletion of Network Files Based on Activity

There are many instances where files are posted on a computer network for access by users. One example is file transfer protocol (ftp) sites. Another is attachment links for email systems where only the web or document link is sent to the recipient instead of the file. In both cases the user must access the network to view or get a copy of the file. In most cases the deletion of these files after they are no longer needed is either based on a predetermined time period or involves manually deletion of the file by the system administrator or file creator. If the file is deleted based on time alone there is a risk that it will be deleted too soon or it may sit on the server long after activity ceases if the time variable is set to long. If the file requires manual deletion then in many cases the file will reside on the system long after its useful life due to oversight by the file owner.

The method disclosed works by incorporating an algorithm that measures the amount of activity (hits) to a site and uses this data to automatically delete the attached file based on predetermined criteria. The criteria used to auto delete the attachment file has four levels of variability. The first level is the Primary Expiration Variable (PEV), which determines how long the attachment file is kept before it is auto deleted assuming no additional hits to the site. The second level is the Activity Variable (AV), which is compared against the number of hits to the site to determine if the file should be kept or deleted. The AV minimum count is one, but it could be set much higher. The AV is measured over a time period, which is the third level, and is defined as the Time ...
