Got 3 files that need to be unlocked using HJ split. However windows has labeled them as TYPE MPG. They need to be type 001 files for HJ split to recognise them. How do I change the file type in windows Vista? Thanks

Is it sufficient to rename the extension from .mpg to .001 ? e.g. video1.mpg to video1.001, video2.mpg to video2.002, etc.. After you are done, you change the extensions back to .mpg. Regards SuatCINI

The label doesn't matter. Windows probably hasn't changed the actual filname - by changing the file extension - but rather is hiding the file extentions altogether. Windows does not automatically change file extensions. Set Explorer to not hide file extensions for known file types, then you'll be able to see the full file name. Open the .001 file and you're off.

Thanks but its not the extensions that are the issue, changing the name or changing programme to open files is not the problem. Rather the TYPE is what needs to be changed and I can't see a way of doing this. HJ split only recognises files of Type 001 etc

I haven't a clue about these binaries but spotted this in Google using the string "hjsplit 001 files": http://www.binaries4all.com/001/ Just wondered if it might be any help? some other bloke...

>>They need to be type 001 files for HJ split to recognise them No, they don't. There is no ".001" file type. That would be the file EXTENSION, which you get by renaming the file. If you can't see the file extension, follow my previous advice to reveal it. This is definitely the problem. Try it. The FIRST file needs to have a file extension of .001, which has nothing to do with its file type. The second file must have a file extension of .002, the third must have a file extension of .003, and so on. Again, this has NOTHING to do with the file type, and EVERYTHING to do with the file extension. HJsplit only needs to open the .001 file anyway, so it doesn't matter if those other files (.002, .003, etc.) are assoicated with HJsplit or not. Open the .001 file with HJsplit and it will start with that file and automatically process the other files. You DO NOT have to open each file individually in HJsplit, nor do you have to associate those files with HJsplit. From the HJsplit manual: "a collection of split parts is set of files having all the same filename, exept for the extension at the end of the file name (.001, .002, .003, etc.) . Combining/joining these split parts is equivalent to restoring the original (pre-split) file." http://www.freebyte.com/hjsplit/manual/

Lowhanging honey - I see, got you, this seems to have worked. Many thanks for the help and patience, really appreciate you taking the time to explain to a layman. Regards thanks also to suatcini and Derek
