I'm trying to upload 10 GB files to S3, but the files are too large.
So I'm looking for a program that will zip then split the file into multiple, smaller files.
Of course, I need the same program to enable me to reconnect the files
My preference is to have a Mac & PC program, but the Mac version is most important to me.
http://www.hjsplit.org/ says it is supported by PC and MAC
there are loads of programs to split files, this one for the PC, called WinSplit http://www.pcworld.com/downloads/file/fid,17120-order,1-page,1-c,alldownloads/description.html
Any binary file splitter, a program that just reads the binary of the file and doesn't interpret it, doesn't add or remove anything. They should combine too.
Also, to combine them on a PC you can use copy /B file1.a+file2.a then they end up totalled in file1.a so you may want to make a backup of file1.a if you want to keep it 'cos it'll get overwritten. If you use copy /B ..+..+..+.. to combine them.
