Replicate Dos commands

[NNNNN]

HI
I wonder if tis is possible

to compoare the text in two files to see if they are equal

the dos command is
comp "file1.txt" "file2.txt" >c:\mycompare.txt

this compares two text files and sends the results to a text file.

can this be done from access

so if I had a form with 3 text boxes
I put my file names in text box1
the file I am comparing to in text box2
and I would like the reult to appear in text box three.

Also

I want to replicat the findstr command

what I want to do is search through all text files in a particular directory
and show the files that contain the text "staff"

I want the results to be sent direct to a table


Thanks for your time
