CSV File Not found on impory about daily-money HOT 7 OPEN

1. Copy accounts.csv & details.csv to /mnt/sdcard/bwDailyMoney
2. Run DM, "Data" -> "Import CSV" -> "Shared-All"

I did that. It's still not recognizing my csv files that are clearly in that 
folder with the csv file extension as 

1. Did you change Preferences -> Working folder in DM ?
2. What are the exactly file names of csv files in /mnt/sdcard/bwDailyMoney ?

I did not change the working folder. I've tried to locate such an option under 
preferences but couldn't. The file names in the bwDailyMoney folder are:  
accounts-20120818-203033.csv and details-20120818-203032.csv

If you didn't change the file name, accounts-20120818-203033.csv and 
details-20120818-203032.csv are not most recent backup file.

You still can import them after changing file names to "accounts.csv" and 
"details.csv".

Then follow the step in comment 1, it should works.

The file names came from the Export CSV feature. Changing the file names 
worked.  THANKS! 

Export CSV will default generate 4 files (assume there is only 1 book)
accounts.csv, details.csv, accounts-0.csv, details-0.csv

If you check "Preferences"-"Backup old CSV when doing export",
DM will backup old accounts.csv, details.csv to accounts-yyyyMMdd-hhmmss.csv, 
details-yyyyMMdd-hhmmss.csv

yyyyMMdd-hhmmss is backup time.
