Does your downloader permit you to specify the range of dates to use for downloading historical data (many do)? If so, just delete the symbols and download for the specified range.
If not, I suspect that you will have to write some code using the file functions fopen, fclose, fgets, and fputs which can read/write the data file. In terms of strategy, I suppose that there are a number of ways to go but one might be to read the data and then within the date range of interest write it to a new file. There are export/import codes in the library that might be helpful.

Surely there's an easy way to create a watchlist of quotes from date x->y? and delete from there?
