I'm trying to read data from a database that I don't know and that has the following structure:

cur
|
|
---- FILE ----
| rs_pers.dat
| rs_pers.fmt
| rs_pers.idx
| ..............
| WS_FTP.LOG
|
---- red7-----
| 77008
| .........
|
---- sys------
| db.DAT
| db.idx
| ........
|
|
cee_ap
name.idx
name.dat
...........
isam.log
tmpout3384.txt


Does anyone know which database is and how to read it ?
Thanks
