The first time I download some split files with .001,.002 and .003 extensions, I was confused about what to do with them. I first thought they were split archives and renamed them to .rar but I got nothing but error extracting the content. I googled out solutions but none made sense till I ran across a software that solved the issue. I was able to join the split files (not archive). Now, I have to explain this: .001 and .002 can either be whole files split into parts or split archives. You’re going to deal with them differently in each cases and there are two solutions I found.
1. Joining .001, .002 as split files
You should first try out this method as it worked in my case. It’s most likely that you’re dealing with a whole file, not a split archive. the file I downloaded the files and they looked like that looked like file_name.exe.001, file_name.exe.002 and so on. It could be file_name.pdf.001, file_name.ipa.exe but you’re likely to see the original extension in this case.
You need a software called hjsplit to join these split files and it’s quite easy to use.
How to use hjsplit to merge / join split files
- Run Hjsplit.exe
- Click Join
- Select Input File and locate the first .001 file.
- Click on Start, this should merge the file. It will locate the rest of the files so far you place them in the same folder.
2. Using 7zip archiver
This is another alternative and you only need it if the file is an archive. Download 7zip from sourceforge and install. This will treat the file as an archive instead and what you’re going to get is the whole content in a folder.
I sill suggest you try out the first method though.

What’s d purpose of this files?
wow, finally got it.. It was really hard to play all different part of a movie smoothly! Thanks for great tutorial!
As explained in the article, they are normal files split into parts for easy uploading. You should’ve come across them if you download heavily from file sharing sites.

I had come across similar files which was split when I unzipped the file on Symbian mobile. Unlike the extensions you stated above, The file extensions i had were of various extensions, the question now is would this software work in merging them together for me?
Various extensions? Can you state precisely how they looked like? I guess hjsplit should work if you cant extract them successfully

Hj Split for windows is the best utility ever to split and join files without much hassle.

The idea is to split the files in files of XX size probably to comply with size restrictions in sites like dropbox, etc.
This is something common in unix, linux and therefore in OSX (as it is based in unix).
to join the files in mac osx the command “cat” is used so:
open a terminal, using the command “terminal” in the spotlight search window, hit enter
A white terminal window will open, then go to the directory where the files have been downloaded, so probably “download”
# cd Downloads
now enter
cat filename1.ipa.001 filename2.ipa.002 >> filename.ipa
where filename is the name of the app, although it doesnt matter what name you give.
that’s it, open the file filename.ipa with itunes.
