Since some noobs like me does not know about Checksum and how to calculate it I share this topic.
You may have seen there is a number called "MD5" together with long digit in some threads. You may be confused what this number for.
Actually, MD5 is a number verifying whether the file you have downloaded is alright or broken, by comparing with the original's MD5.
Some can compute this number using solidexplorer.apk in their phone however some would like to figure out this number before transferring their file, specially a big zip into their memory card. So here is a very easy way to calculate this number by a software in windows.
WinMD5 is a small and easy tool to calculate md5 hash or checksum for different files (including files larger than 4 GB).

Features:

  • Supports almost all Windows platforms including Microsoft Windows 95, 98, 2000, Me, XP, 2003, Vista and Windows 7.
  • Fast and multi-threaded. It can compute a 2 GB file less than 1 minute.
  • Supports big files larger than 4 GB.
  • Low resource usage. It uses less than 5 MB RAM.
  • Don’t require .NET runtime installed. It is a standalone EXE file and the startup is speedy. There are MD5 tools for Windows on the market, but most of them requires .NET runtime and they may take a few seconds to start. This is also the reason I wrote the program.
  • Supports “Drag & Drop”. You may either select a file, or drag and drop a file to the program window to get the MD5 hash value.
  • Supports verification of original MD5 value and current MD5 value.
  • Most important, it is FREE. No spyware or adware bundle.
  • Small size, an effective and tiny tool for data security.

Just extract the exe file and address you file. It would begin to calculate MD5, then click verify so see number is matched or not. That's it.

Thank you for your post.

As an addition, almost all download managers (free or otherwise) automatically calculate this for you after a download and report any discrepancies as well. :)

There are several Browser Plugins as well which are quite handy. That is one area to look into as well.

But yes a handy tool is always good to have :)

A quick applications for this stuff is also HashCalc, it can show u several Hashes so you can compare it better.
I use it all of the time and got no problems with it.

I've never used this app but it looks like you are on the right track. Now you have generated the checksum by finding file on your phone you need to go to website or wherever you have the reference checksum stored, highlight it and copy it, then just click the clip board icon as shown on your screen, then press the compare button at the bottom.
