Advanced CheckSum Verifier - the SFV and MD5 checksum utility for Windows    Advanced CheckSum Verifier
 

Quick start

For launch the program, execute the file ACSV.EXE. The main program window should appear.

To start work, it is necessary to specify in a "Folder" field the folder with files. You can press the button at right side of this field to invoke the folder selection dialog box.

Folder selection dialog box
Pic.2.Folder selection dialog box.

Now, if the default settings satisfy you, it is possible to press button "Update" or "Verify" to begin, accordingly updating of checksum files or check of files. The program will start processing files in the specified folder, progress bar at the bottom of the main window will indicate how many files are processed, and window title will show percentage of work. The logging window will display the messages arising during processing.

Please, wait end of work and look through the contents of a log window.

Typical scenarios.

Check of the received files.

We assume, that you have downloaded some files from the Internet and now want to be convinced, that files were downloaded without errors. Fortunately, the owner of a site, whence you have received files, together with files has laid out also checksum files. And you have downloaded them together with files.

For example, let the downloaded files are in the folder "C:\Download", and the checksum for each file are stored in a file with the same name, but with additional expansion "md5".

To check up these files make the following:

  1. Enter into a "Folder" field a path to files: "C:\Download"
  2. If in this folder there are subfolders check a "Include subfolders" box
  3. Enter into a "Checksums file" field a mask for checksum files: "*.md5"
  4. Press the "Verify" button
  5. After end of work look the log and make conclusions.

Creation of checksum files.

We assume, that now you have decided to lay out some files on the Internet. And too, for caring of visitors of your site, you also have decided to place together with files their checksums.

For example, suppose, that you have collected all these files in one folder "C:\Upload", have decided that for the checksums the MD5 algorithm will be used, and that for each file there will be a separate checksum file with additional extension "md5".

To make this it is necessary to do the following:

  1. Enter into a "Folder" field a path to files: "C:\Upload"
  2. If in this folder there are subfolders check a "Include subfolders" box
  3. Enter into a "Checksums file" field a mask for checksum files: "*.md5"
  4. Make sure that the "Create SFV files instead of MD5SUM " box is clean
  5. In the "Create checksum files." group select the "…for each file" item.
  6. Through the system menu invoke the "Options" dialog box, and in this dialog box, in "Checksum files headers" group, select "Add standard ACSV headers" item.
  7. Press the "Update" button
  8. After end of work look the log and make sure, that all files are successfully processed.

Now contents of the "C:\Upload" folder can be placed on your site.

Recording CD-R(W).

Assume, that you need to write down a plenty of files on a compact disc for transfer to the customer in the other city. Or, you need to free some space on a hard disk and for this purpose you have decided to move old files to compact disc. In both cases, it is necessary to be convinced that all files has been recorded correctly.

Let's assume, that all files are collected in one folder "C:\MyFiles", and the drive for recording on CD - R (W) is established as a disk "D:". Because for us reliability in this case is very important, we again shall choose the MD5 algorithm. And because there is no necessity to create a separate checksum file for each file, we will create one file for entire compact disc.

This time the sequence of actions will be such:

  1. Enter into a "Folder" field a path to files: "C:\MyFiles"
  2. If in this folder there are subfolders check a "Include subfolders" box
  3. Enter into a "Checksums file" field the name for a checksums file: "md5sum.lst"
  4. Make sure that the "Create SFV files instead of MD5SUM " box is clean
  5. In the "Create checksum files." group select the "…one for entire folder tree in tree root" item.
  6. Through the system menu invoke the "Options" dialog box, and in this dialog box, in "Checksum files headers" group, select "Add standard ACSV headers" item.
  7. Press the "Update" button
  8. After end of work look the log and make sure, that all files are successfully processed.
  9. Launch CD-R(W) burning program and write down files.
  10. After end of burning, return to ACSV
  11. Enter into a "Folder" field a path to files on CD-R(W): "D:\"
  12. Press the "Verify" button
  13. After end of work look the log and make conclusions.
