    What's a good (& free) file synchronizer?


    What app do you guys use to diff/sync files? Only requirement I have is that it's free.

    MS Synctoy - you have to run it when you want to sync, doesn't do it automatically, but it works well.

    Alternately, you can write your own xcopy script and run it as a scheduled task, such as:

    xcopy O:\OMATE32\DATA\*.* "G:\DATA" /e /h /v /d /r /y

    to make multiple backups just add more copies of same script in same file like this:
    xcopy O:\DATA\*.* "G:\DATA" /e /h /v /d /r /y
    xcopy O:\DATA\*.* "H:\DATA" /e /h /v /d /r /y
    xcopy O:\DATA\*.* "I:\DATA" /e /h /v /d /r /y

    ************************************************** *

    Instructions:

    1. Create a folder named "DATA" on another drive of same computer or another computer on your network - this will be where you backup is stored. (I personally installed a 4GB thumb drive and use that - I used to take it home once a week for backup, but now I just use carbonite.com.)
    2. Open Notepad, copy the script into a blank file.
    3. Change the "O" to the drive where you keep your main DATA folder. (probably C)
    4. Change the "G:\DATA" to the backup location you created in Step 1
    5. Save the file as "backup.bat" somewhere safe where it won't be deleted.
    6. Open Windows Scheduler, find this file and set it to run once a day at a certain time when computer is on but OM is completely closed out on all computers (we use 10pm) It will search your data folder for changed files (scans, etc) and then update the backup folder.

    is xcopy supposed to overwrite every file or check if the destination is the same and then not copy?
    atm it overwrites all and i have to use the /y flag...
    would be cooler if it checked first...`?

    screenshot, in the future do not bump 6-year old threads; make a new one.

    xcopy is a lower level command in DOS/Windows to be used by system administrators and/or for integration into larger functions/applications. It is not intended as a user-level command, so it does not have any "smart" features; those should be implemented by the admin.

    What do you want to do? Back up files to another disk, or online?

    Pretty much all backup applications perform the functionality that you are asking for, including the standard windows backup.

    If you want to backup online, you could use Google Drive or Dropbox.
