Concat

ConCat/Split is a Windows Explorer context menu extension that provides two complementary facilities:
· A split facility that lets you easily convert a single large file into several smaller ones. You can copy these smaller files onto floppy disks, or send them through email facilities that will not cope with large files.
· A file concatenation facility that performs the same operation as the command line "copy /b SrcFile1+SrcFile2 [+SrcFileN] DestnFile" operation.
Using this application, you will be able to append as many files as you need and save the result as a new file, but you can also choose to overwrite one of the source files.
Note: The concatenate facility will only join raw split files. It will not intelligently join separate structured files such as audio, video, or word processor documents into a usable composite file.Limitations in the unregistered versionThe registered version of ConCat adds the following advanced features:
The ConCat dialog box has the ability to re-order the files you want to join, making it unimportant to select the files in the correct order in the first place. Select the file in the Copy list box and use the up and down buttons as required. The buttons respond to the keyboard accelerators Alt+U & Alt+D.
Automatically selects the correct destination filename for files that are split and retain their Split/ConCat naming convention.
The ability to automatically create a batch file that will rejoin the files easily on any MS-DOS compatible system that does not have Split/ConCat installed.
The last split size is saved between uses.
