FILE SPLITTER

• -An indigenous program to split merge any kind
  of file

3
Definition

• The File Splitter is a free Windows program
• that will split any file into pieces of any
  size
• and later combine the pieces to form the
• original file.
• You can directly write on floppy disk or may
• split it on hard disk later on any folder or
  on CD or can send through e-mail.

4
Need?

• A floppy disk is often the only possible mean for
  transferring the file, but if the file is larger
  than 1.44 megabytes, it won't fit on a single
  floppy.
• Many e-mail systems place a limitation on maximum
  size. What if you want to send a file larger than
  maximum capacity?
• Also for the CD maximum size is about 700MB.
• Which simple mean do you find to get a video
  file of size larger than its capacity

5
Approach

• The software has been made in C-a well known
  computer language as a program.
• C has basic high low level I/O commands that
  make the task of creating, opening, reading
  writing in files much simpler easier.
• It also provides inbuilt functions which can
  fetch file path, can read data directly from
  floppy disk.

6
Principle

• Fetch the path of the file to be split.
• Create a text file which keeps track of filename,
  extension, size etc.
• Create a new folder to contain the split files.
• Read data from the source file.
• It is read in the form of a chunk of bytes(512
  bytes) i.e. buffer.

7
Principle

• Write that much number of bytes in the
  destination file.
• Continue to write till the end of the source
  file.
• Close source file.
• Close destination file.
• Care is taken to append appropriate extension to
  the destination split files

Working Representation
10
Quick Split

• A floppy disk of 1.44 MB size normally contains
  80 tracks.
• Each track is again divided into 18 sub-sectors,
  each of 512 bytes.
• We write chunk of 512 bytes to each sub-sector
  till the end of floppy disk.
• Before writing on floppy disk, it shows the
  available space for writing purpose.

11
Quick Merge

• It takes the text file from each floppy disk into
  which we have stored our pieces.
• It compares the password of text file regarding
  the sequence type of file to be merged.
• Encountering any kind of mismatch it shows the
  appropriate error message.
• It follows the reverse process of splitting.
• After merging the original file runs in its
  authentic format.

12
Custom Split Merge

• We have placed no limit on the number in which
  you want to split the given file.
• We store these split files in the current
  directory with one restorable file which contains
  the genuine specifications of file.
• You may transfer them to CD or floppy disk.
• All the split files are restored using .rst
  file.
• So we customize the split option.
• Also separate folders are made to avoid confusion.

13
Features

• User friendly profile
• Standardized GUI which follows copying process
• Gives available space on floppy disk in case of
  ambiguity
• Creates separate split restored folders
• Basic C-language code
• Gives the path of split restored files

14
Advantages

• Splits files of any size you specify.
• Allows to split any kind of file (mp3,mpg,jpg)
  merge.
• Can directly write on floppy disk
• Recreates original file details
• MP3 etc individual split files also run

15
Applications

• Large files (size gt 1.44 MB) such as a mp3 file
  can be conveniently taken on floppy disk
• Extra large files (size gt 700 MB) such as video
  file can be split, stored on hard disk, written
  on CD, restored back.
• Split files can be sent through e-mail.
• As multi-purpose cutter like mp3 cutter which is
  generally not available

16
Scope Limitation

• It can also split .exe file. Exe file can be
  attached to one of the split files the split
  files can be restored on second node without the
  installation of the software.
• As we split a .dat file, first part as having
  header, runs but the software cant run the next
  split files as they dont have the headers though
  they can be restored perfectly.
• So attaching .exe appending headers could
  possibly be the future developments.

Thank you

• We are grateful of OPUS organizers for compelling
  us to put our skill to create such indigenous
  program.
• Thank you for listening us.
• We would also like to share our joy with our
  senior friends who prevented our morale from
  going down.
