I have a friend who has a file on her computer that is 57 GB. It is listed as a FILENAME.XLS
The friend also has another system that has two of these ".XLS files" on them with similar file names that are 932 GB and 157 GB.
The file is definitely NOT a XLS file...
Does anyone have any ideas on how to figure out what this file is? My initial thought is that it might be some kind of video archive or something (based only on the file size).
