Why the comparing takes so many hours??

  • I started comparing 2 files yesterday.
    The first file contains 3 million lines, the second file contains 1 million lines.
    Each lines in the line is approximately 20 characters.
    After 15 hours the program still not finished
    (the same screen and status bar)
    Why does the comparison take so long or maybe something wrong?
    How to check if the program in the background still compare
    or maybe there is any error and it will never end?

    Hi Martin,

    Unfortunately Compare plugin takes A LOT OF TIME comparing some kind of files (that is because of their content, not their type). I suppose your files are falling in that group.
    It also doesn’t show a meaningful progress in that case because the compare process is not linear and there are several compare stages. Your comparison is having troubles in the early stages (because of the file contents specifics) but it is very possible once that stage is over the other stages to go almost instantly.
    I’m pretty sure it is still comparing, it hasn’t crashed but there is no way to check how much time it will take it to finish.

    Having said that leads to the conclusion that Compare plugin is pretty useless in your case.
    You’ll need to kill the running Notepad++ instance from the Windows Task Manager because the progress Cancel button won’t work in that situation.

    I suppose it’s not the case but if it happens that your files are not confidential I’ll appreciate it if you send them to me so I can further check what’s happening.
