If all files having same Metadata,
Select Read method as 'specific file(s)'
then u Can add as many files as you want to run by selecting 'file' property from the 'available properties to add'.
It locks like below:
File= /dsg/work/temp/Employee1.txt
File= /dsg/work/Employee2.txt
File= /dsg/Employee3.txt
Read Method= Specific file(s)

Answer / venkata ramana
To read given number of files, one can use follow below
In the sequential file stage, Use
Read Method =File Pattern
File Pattern=`ls /* | head -<Number of files to be read>`
For example, I had 5 files, with similar pattern (as
date*.txt), in working folder say "/data/working/". If we
want to read three files out of these five files, one can
use following command:
`ls /data/working/date*.txt | head -3`
Just modified Venkat's Answer based on tested job.

Answer / pooja
To read multiple files in a sequential file follow the
below process..
1. Enable "Allow Multiple Instances" in the Job Properties.
2. Add a job parameter in the sequential file stage where
the input file needs to be defined.
3. Compile and execute the job.
4. During execution, a value needs to be passed to the job
parameter..here pass the input file path placed in
different directories.
5. Execute the job for all the multiple files using the
same job by passing the input file path for each run.
6. An invocation id needs to be provided for each run. This
id indicates the no. of times the job has been executed.
Can be observed in the log.
