Internet Download Manager (IDM) is a download accelerator and file organizer that manages the download of many types of files from the Internet.Has IDM ever not been able to complete a download perfectly? Maybe it's stalled at 98% or a number very close to 100% and stops downloading altogether. Then, instead of the file you wanted, you get a totally corrupted download that you cannot use.
IDM works by dividing the file into between two and ten parts in order to accelerate the download. At the end of the download, IDM combines all the file parts into one file. Sometimes, one of the file pieces was corrupted, in which case IDM could not merge the file and complete the download.
This can be especially frustrating when you're downloading large files with a slow connection. You wait for what seems like forever for your download, and then it gets stuck right when it was about to finish, and you can't start it back from the beginning.
You only need this two things to fix data corruption on IDM:
Your system needs to have the capability to resume download, which means that if you fully stop downloading, the server should be able to support it so it can start it back at the point where it was stopped.
You need a type of software called a file splitter and joiner.You can download Hjsplit software here.

Step 1:
Go to the IDM temporary file location, where IDM stores the file parts before completing the download
Look for and select "Options" in the IDM Toolbar.
Step 2:
Find and select the option to "save to" and search for "temporary directory" (see image above).
Copy the address. For example: C:\Users\rixpro\AppData\Roaming\IDM\DwnlData\
Step 3:
Find the folder of the corrupted file (the one that failed to download completely). For example, if you're downloading a file named softwarehacks26_1, there should be a folder with a name very similar to the one that you're downloading.You can find the folder by searching for the file name and then opening it. Sorting the files by file size or date may also help you to find the folder.
Step 4:
Once you open the file, you'll see it's been divided into different parts, usually between two and fifteen.
Not all of these files are corrupted, and you will be able to combine some of them.
Minimize this window and start your download again.
You should be able to see the IDM download progress bar indicate the combination of parts that are not corrupted. However, you still won't be able to complete this because there are still corrupted file parts left.
Close the download and maximize the IDM temporary directory.Now you should see that some parts are now combined and there are only two or three files. These are the ones that can't combine at the end because the file is corrupted.
Step 5:
Now you have to use the file splitter and joiner to remove the corrupted end from the file parts. I'm not going to explain much about how to use the file splitter and joiner because the software is usually very easy to use.
Open one file part with the software and split it so that one part contains 250 - 500 KB. For example, if your chosen file part is 10 MB, use the file splitter and joiner to split it into 20 parts so that each one will be 500 KB. Don't forget to delete the original file part. Now you have 20 parts with name extensions like filename.001, filename .002, filename.003 [...] filename.020
When you reach this point, delete the filename.020 (which is the corrupted end), and join the other 19 parts back together again using the software. You can also use the software settings so that the other file parts are deleted after you combine them again.
Do this for the remaining parts, also removing their corrupted end.
Now, go back to IDM and resume downloading and your download will finish perfectly.
