How to repair a damaged RAR file?

How to repair a damaged RAR file?

(OP)
Hi guys!

I've download a big file more than 4 Gb and finally after several weeks i got a message during extracting from WinRAR, that my rar file is damaged.

Can someone help me with such complicated situation?

RE: How to repair a damaged RAR file?

Go somewhere with more bandwidth, and download it again.
Even better, retrieve it from a different archive, using a different transfer protocol.

(
In general, all compression schemes, like RAR, remove all redundancy from a file, so a single bit glitch makes it nonrecoverable.

I'm guessing they're using bitTorrent or similar. You basically have to download again. Or just buy it.

Try next one manually solution in WinRAR:

<Open the file in WinRAR (download from internet if you don't have one).
<Press your right mouse-button.
<Click on "Repair archive", or press Alt+R.
<Click on Browse button and select a folder where you want to keep the repaired archive.
<There will be two options ("Treat the corrupt archive as RAR" and "Treat the corrupt archive as ZIP").
<Select any one of your choice (or see which one will work) and click on OK button.
<Go to the folder where you have kept the repaired archive and open it (Repaired archive will be named as rebuilt.*.rar or rebuilt.*.zip, where * is the name of original archive).

If the guide above isn't effective for your damaged .rar file, then...
