Name Format For Filtered Files

[suyanglu]

1.Please use this format for filenames: dictindex_name.csv Please do not add any other symbols to the name. (someone add sign of square root)

2. Do not use space in the filenames.
3. For the file ending, make it clean. Save them in dropbox as xlsx or csv format. Avoid repetitive ending like: xls.csv.xlsx.
4. Frank make sure all the files you export to dropbox are readable with right encoding.
