If the file is repaired you’ll see output along this lines of the following: Building 03 It will look something like this: rar r /Users/YourName/Downloads/the-big-download/the-big-download.r03 You should now see the full path of the file appear after the rar r part you typed. Grab the file in Finder and drag it to Terminal. Go to finder and locate the first damaged file you found in the RAR test you performed in Step 2. It saves having to type long paths and avoids making errors. TIP: Also remember you can simply drag folders and files from Finder into Terminal and their full path will magically appear in Terminal. So it’s rar(space) r(space) – don’t hit enter just yet. Note, there is a space before and after the free-standing “ r“.
Type in the following into Terminal at the command line: cd /Users/YourUsername/Downloads/Repaired-Archive-Files/ So the first command (cd) in the following example is for that purpose. With all the RAR and UNRAR commands, any time files will be generated you need to first change the active directory (in Terminal) to the location where you want the output files to go. Run Terminal.app (type Terminal into Spotlight search). After that, you will have now identified which files in the archive set or batch are damaged. Step 2įollow the instructions in this article to test the archive for possible damage / corruption. If, however, the files are all complete but one or more have errors, they could likely be repaired.įollow the instructions in this article to install RAR and UNRAR. You may be able to resume the download or you may have to re-download that file. If the files are exactly 100 MB each, and you have one in the batch that is say 99.999 MB then the file is complete.
Of course if any of the files in batch are incomplete a repair won’t be possible. This means you can test an RAR file for corruption, and it means you can often repair a RAR file that won’t extract.
They also contain error checking data (CRC data) in them. RAR files usually contain a repair segment within them. If all the files are complete they should have the same number of bytes (except the last file which will likely be smaller than the others), then it is possible some data was corrupted. If you’ve ever download large packages of files split up into a batch of RAR files, you may have had the situation where the RAR can’t be expanded due to an error.
