I just found a history file that has over 57 million records and is taking up a good share of disk space. This is a file that contains 1 field per record of mixed data. There is nothing that resembles a time stamp of any form in the record.
I would like to at least delete the first 50 million records (I have no idea how old some of this data is, but I have been here for 2 years and didn't even know the file existed. So I can't imagine the data is very important after a few weeks/days.)
I know I could write a program to loop 50 million times and read/delete each record. But looking for something that might already be in place w/o creating this little program and perhaps be less of a resource hog while it runs.
