Jackup is a simple and easy to use backup tool made in Java. Choose two folders, source and destination. Jackup scans all the files and subfolders, and tells you what files have been changed and which files don't exist in the source anymore.

There are three ways to compare files: date/time, date/time/size or date/time/contents. If you want to be absolutely sure that files are identical both in the source and destination, choose the last option.

Usage:
Once you have the JAR file on your local system, you can execute it by double clicking on the file. If this does not happen, the reason might be that the "Executable JAR" file type was not successfully registered with Windows by the JRE installer, so it does not know how to handle the file. If this is the case, you can execute the file manually with the command line:

Open an command line
CD to the directory where the JAR file is located
Type: C:Program FilesJavajre1.5.0_01binjava.exe -jar Jackup.jar (Note: if you installed the JRE to a different directory than the default, then replace C:Program FilesJavajre1.5.0_01 with the appropriate directory).

Requirements:

· Jackup needs Java JRE release 5.0 to run
