This new program will allow users to find duplicate files for two main purposes. To either save space, but also to make sure that there are duplicate copies for security purposes. The program scans all attached drives and network drives and give a sumary of where space could be saved or important copies moved to.
What is a duplicate file?
A critical question, and CnW-FM will have several options. The very simplest will be files with the same name and same length. In many cases this will be the quickest search, but at times there may be files of the same size but different contents. Date may or may be important. It is possible to open a document and save it without making any changes, so two identical documents, but different date.
An ultimate test for seeing if a file is idential is to take a digital signature of the file, eg CRC32 or MD5. These signatures are calculated by examining the contents of a file - by default limiting to the first 1MB of data. This will show an identical file, even with a very different files name. Forensic investigators will often use this mode to find potentially hidden or renamed files. This is very safe comparison, but as it requires every file to be full read, it will be slow.
Which drives?
CnW-FM will scan all local drives, connect USB drives and mapped network drives
