Use this diff utility to compare text, binary files (HexDiff), complete folders and SD-cards.

It can compare documents too (the unformated text of them).

+ And you can also store information about all the files located on your directories, to detect changed files later.

The functions of DiffTool in detail:

1. Compare 2 Texts:
- supports:
text files,
clipboard text,
source code,
text of documents (Microsoft Office and Open Office),
compiled Android XML (diff Manifest file)
- supported file formats:
ASCII, ANSI, ISO-8859-1, Latin1, CP1252,
UNICODE (UTF-8/16/32 little and big endian),
DOCX, XLSX, PPTX,
ODT, ODS, ODP,
DOC, XLS, PPT, RTF(latin1 only)
- ignores differences on whitespace
- ignores end-of-line format differences (Unix,Windows,Mac)
- search for text or line numbers

2. Compare 2 Binary Files (HexDiff):
- files can have any format
- HEX and ASCII display
- checks differences on whitespace and end-of-line
- search for HEX, ASCII text or the address
- when having tons of bytes which differ, showing all details can take a while

3. Compare 2 Folders:
- checks if files are 100% BIT EXACT
(to compare by HASH run 4.)
- include or exclude subfolders
- compare the content of ZIP, JAR, EPUB and APK
- search for file names
- use double-click to compare/merge files or to merge/synchronize folders

4. Store Folders State:
- Stores the state containing the info of files located on your directories. By viewing this state later (see 5.) all files changed, since the state has been stored, are displayed.
- This feature can also be used to compare two SD-Cards. Store the state of card 1, after it, replace card 1 by card 2, view the stored state (see 5.) and all the files which differ will be shown.

5. View Stored Diff File:
- loads stored diff's, also of other Diff/Patch tools
- loads a folder state file and checks changes

6. View the Text of a File:
- views any text file, the text of supported documents and clipboard's text
- views AndroidManifest.XML of any APK

7. View a Binary File:
- Hex Viewer

8. FGrep:
- search for text in files and documents (find in files)

On the Result Screens:
- colors:
red = old content A
green = new content B
red/green = changed content
yellow = inline changes
black = identical content, A=B
- pinch-to-zoom
- export results as text
- works on big and small displays! (uses an integrated view instead of 2 panels)
- you can search for text, file names and line numbers
- press long on a file to open it
- pressing long on the left side, opens a scrollbar having diff info too

DiffTool is also an ideal source code viewer for all developers to check their changes on C, C++, HTML, PHP, C4droid *, Python ® **, AIDE ***, Java ® **** and any other source code.
