Please report any bugs to comicinker@gmx.de. # # Featues: # Splits one file # Resulting file name: "file name.dum_000" # Prepared file sizes as well as manual input # Don't touch the origin file # confirm overwrites # Warning if more than 30 files (optional) will be created # Creates Md5 sum (optional) # # Don'ts # Won't check for disk space # Won't split in more than 1000 files # # You can merge your files in a terminal with cat filename_* > new_file # Or use the merge script File_Merge for Nautilus from me # To check the file md5 sum type md5sum -c yourarchive.md5 in a terminal # or use the File_Merge script from me # # This program is free software.
