2. from those 1000 bytes, generate an SHA1 hash.

3. store the hashes, file size, and file names in a list

If you know that the maximum number of bytes you're going to read is 1000 then you could have used an inexpensive hashing algorithm.

Were you initially planning on hashing the entire file or something?
