you know the current date - go back the required number of days - generate file names and delete them using remove()

an alternative if they were named something like 1jan2007.doc, 2jan2007.doc, etc, would be to delete them month by month use system(), e.g.

    system("del *jan2007.doc");

The program automatically makes file everyday by taking system current date.In this process when the no. of file becomes 150 i want to delete first 100 files.This is online program for a data acquisition.Remove() removes a file ata time and the user has to supply the file name to the function but in this case the program has to automatically delete first 100 files.How can i do it.Pl. help me out.
