I'd like to do a file 'split' on a document that's a bit too big to make it through the mail server. I can split the document with Opus, but the recipient doesn't have Opus, so, can they do a 'join' on their side without it ? If so, can you recommend a good piece of software to do this (preferably free and open-source) ?
I split the files using Opus (generating file.001, file.002, file.003 etc.), and then joined the split files back together using the command prompt, with the command line:
Copy /b *.00? JoinedFile.odt
It seems as though the splitting and joining processes use an agreed upon standard, since I can use different software for splitting and joining (mix & match), without any compatibility problems.
In this case, the user to whom I'm e-mailing the split document doesn't have advanced computing skills, so I'd rather not inflict the Windows Command Prompt on him.
I found a utility called "HJ-Split" ( hjsplit.org/ ) which runs in portable mode, and executes both splits and joins from a user-friendly GUI.
The utility is only 197 KB in size, so I can send it along to the recipient as an e-mail attachment. The only gap in functionality is that the utility doesn't offer an option to UUEncode or UUDecode (which Opus does), but I don't think this would be an issue for most.
