Hello:

 

I have a big file (suppose 100 MB) and it is splitted into 10 parts in .rar extension. Now the question is if I lost any part, is there any way to extract the remaining parts by joining? If so, please tell me in details.

Hello, and Welcome

 

When you say lost, is one of the parts corrupted? If so, you may be able to repair it using WinRAR's repair tool. What part was lost or broken?

 

See this thread.

Also welcome to BC !

 

If you are using WinRar it usually gives an indication where the failure occurred - by that I mean which section is damaged/corrupted. A simple solution would be to download the damaged file part again, or get another copy of it and use that instead of the faulty piece.

 

It would be unusual to break a file of only 100MB into 10 parts unless it was sent by e-mail, in which case contact whoever sent you the file to re-send it.

See below from Here: Although the question is a bit different .. it is basically the same problem.  If this is a video file you can take any one of the volumes and copy the volume to the name of the missing file.  This will allow you to join all the files together but whichever file you copied will 'show' the output of the video of the file you copied and not the missing video.  A better solution would be to create a new volume from the original and make sure you choose to save recovery data in the options.

 

If when the .rar volume was created you/ (whoever .rar'd the file) did not choose to store a recovery record than it may be impossible to rebuild the missing .rar.  You can try the recovery method described below.

 

Q:I failed to extract files from a solid multivolume RAR archive because one archive volume was damaged (bad floppy diskette). Help me!
 

A:First of all, you should use RAR recovery record when storing archives onto unreliable media such as floppies. Generally, it is not recommended to create solid archives in this case. You should use the normal (non solid) mode instead.

If you have a damaged volume of a solid archive, try to repair the damaged volume. It helps if you used RAR recovery when you created the archive. You may check for the presence of a recovery record in the archive by using the Show information command. Rename recovered volume, fixed.arcname.rar (if recovery record was not used, WinRAR builds only rebuilt.arcname.rar) to the actual volume name and try to unpack your archive again, starting with the first volume.
