To combine files on Windows:
Say you split a file named Report.doc into the chunks Report.doc.a.split, Report.doc.b.split, ... Then in Windows from the command prompt run:
copy /b Report.doc.* Report.doc /b
If you split a file with Archiver on your Mac then you can combine the files on Windows.
Say you split a file named Report.doc into the chunks Report.doc.a.split, Report.doc.b.split, ... Then in Windows from the command prompt run:
copy /b Report.doc.* Report.doc /b
Note that the above will not work if you selected the “Compress” option when splitting files.
If you ticked “Checksum” you must delete the checksum file (the file with ending .chksplit) before running the command.
