Abstract

A computing system performs file conversion upon format expiration. A computing system evaluates a risk of expiration of a first format associated with a first format object. The computing system determines if the risk of expiration is above a threshold. The computing system identifies in response to determining the risk of expiration is above the threshold, one or more files stored in the first format for conversion. The computing system converts one or more files stored in the first format to a second format. The computing system saves the one or more files in the second format.

First claim

What is claimed is:

1. A computer-implemented method for file conversion upon format expiration, the method comprising:
receiving, by a computing system and based upon a first schedule, a command to perform a format expiration check;
evaluating, by the computing system, a risk of expiration of a first format associated with a first format object, wherein the first format object contains information which allows the computing system to analyze respective content of respective files in the first format, and the evaluating includes evaluating a market share of one or more applications that support the first format, evaluating a release frequency of one or more applications that support the first format, and evaluating a number of applications that support the first format;
determining, by the computing system, if the risk of expiration is above a threshold;
identifying, by the computing system by querying a record of associations comprised of key-value pairs between files and formats using format objects and in response to determining the risk of expiration is above the threshold, one or more files stored in the first format for conversion by selecting a subset of the files stored in the first format based on one or more importance values associated with the files;
identifying, by the computing system, a second format based on information stored in the first format object and information stored in a second format object associated with the second format;
converting, by the computing system and on a second schedule automatically selected by the computing system based upon system usage, one or more files stored in the first format to the second format;
saving, by the computing system, the one or more files in the second format by overwriting the one or more files stored in the first format; and
outputting, to a user interface, an indication that the one or more files were successfully converted and saved in the second format, and the indication comprises, for respective successfully converted and saved files, a respective file name, the first format, and the second format.
