[junaidahmed]

As I using Samsung Galaxy Tab 7.7,In my device i can read data but not able to write data in external sdcard (copy,delete,rename folder).Pls advise how to solve this issue.

Many vendors limit external cards to read-only to prevent corruption.
If you are rooted you can run 'mount' to see what it is mounted as.

If it uses a full size card, there may be a write protect switch on the card itself.
