## About Fast File Splitter and Joiner

You have a file that will not fit somewhere, and you would like it to be in pieces. That is the whole job, and it should take about four seconds.

## Two buttons

Split, or join. That is the choice. There is no settings page, no preferences, and no options to read through before the app will do anything.

## Three sizes

Small, medium or large. No part counts to divide out and no numbers to type — pick the one that sounds right and the pieces come out at a sensible size.

## Nothing held back

Every part of this app works. There are no add-ons, no unlocks, no watermark and no piece count waiting behind a second purchase.

## It still takes a batch

Simple does not mean one at a time. Drop in as many files as you like and they all go through in one pass, and a selection sent from Explorer's right-click menu arrives in one window rather than one per file.

## Joining puts it back exactly

Drop the parts in and the original comes back byte for byte. If one is missing it is named before anything is written, so you never end up with a file that is quietly incomplete.

## Nothing happens to your original

Splitting reads the file and writes new parts beside it. The original is never modified, moved or deleted, and cancelling leaves nothing half-written.

## On your PC, and nowhere else

There is no account, no sign-in, no upload and no telemetry. The app has no network code in it at all and works with the connection turned off.

## What's new in 2.0.6

-   Now takes a whole batch. Earlier versions handled one file per run; drop in a folder and all of it goes through in one pass
-   Three preset sizes replace typing a part count, so there is nothing to work out before pressing a button
-   Drag and drop from Explorer, and a right-click selection of many files opens one window instead of one each
-   A missing part is named before joining writes anything, rather than producing an incomplete file
-   Progress for each file and for the batch, and a run can be cancelled cleanly
-   A redesigned interface, in light or dark, and it can follow Windows instead if you prefer
