it is a type of file where file organization is indexed and file accessing mode is sequential.when u create a file as indexed then a file will be created with ".idx "extension and with a record key value.based on the recordkey value records will be arranged in the file.
access-mode sequential means we can access records sequentially.

Indexed Sequential file is a file which creates an index record for each record on the bases of record key. So that we can access the records directly with help of this indexed key. Indexed keys are stored in a specific predefined order . ie. Ascending order.

Change of values in .idx file would take the file into bad file status whenever it is accessed.So, be careful on hanling it.
