sfk split partsize inputfile [outputfilebase] [-nov[erify]] reads and splits inputfile into output files of specified size. if output files exist already, split asks if it may overwrite; specify -yes to overwrite outputs without asking. partsize syntax: 100000b , 100k = 100000 bytes 2000000k , 2000m , 2g = 2 giga-bytes if outputfilebase is omitted, outputfilenames will be: inputfile.part1 inputfile.part2 inputfile.part3 ... if outputfilebase is given, .part1 is appended to this. options -yes always overwrite existing output files. -nov[erify] no verify after split. -altsize use different method (fseek) to read the file size. -getsize=n[:d] before splitting, read file size n times with a delay of d milliseconds (default=100). -verbose be verbose about file size results etc. -buffer=xm set I/O buffer to x MB (default=100 MB). -update do not rewrite existing parts of full size. useful when splitting repeatedly a growing input file, e.g. during a download. -update implies -yes. -dig[its]=n set minimum number of digits used for the .part extension. since sfk 1.6.5, sfk join will autodetect the number of digits. if output will be joined with older versions of sfk then -digits must stay default (1). -text split at line boundaries if possible. cannot be combined with -update. performance notes the operating system may cache output files, writing to disk in background after sfk has finished. subsequent split commands may run slower, even if -noverify is used. examples sfk split 2g c:\bigfish.avi d:\transfer\easy.avi splits bigfish.avi into easy.avi.part1, .part2 etc. to rejoin the files, use the sfk join command: sfk join d:\transfer\easy.avi.part1 e:\full.avi joins easy.avi.part1, .part2 etc. into full.avi splitting text files by no. of lines: this is not yet supported by sfk, but for example the cygwin split command supports this. cygwin is a large package of commands, requiring some installation. if you have it installed, type for example split --lines=10000 biginput.txt outprefix which creates output files outprefixaa, outprefixab etc. see also: sfk partcopy copy a single byte block from a binary file sfk hexdump dump parts of a file for further analysis sfk snapto joins all text files of a directory sfk split partsize inputfile [outputfilebase] [-nov[erify]] reads and splits inputfile into output files of specified size. if output files exist already, split asks if it may overwrite; specify -yes to overwrite outputs without asking. partsize syntax: 100000b , 100k = 100000 bytes 2000000k , 2000m , 2g = 2 giga-bytes if outputfilebase is omitted, outputfilenames will be: inputfile. part1 inputfile.part2 inputfile. part3 ... if outputfilebase is given, . part1 is appended to this. options -yes always overwrite existing output files. -nov[erify] no verify after split. -altsize use different method (fseek) to read the file size. -getsize=n[:d] before splitting, read file size n times with a delay of d milliseconds (default=100). -verbose be verbose about file size results etc. -buffer=xm set I/O buffer to x MB (default=100 MB). -update do not rewrite existing parts of full size. useful when splitting repeatedly a growing input file, e.g. during a download. -update implies -yes. -dig[its]=n set minimum number of digits used for the .part extension. since sfk 1.6.5, sfk join will autodetect the number of digits. if output will be joined with older versions of sfk then -digits must stay default (1). -text split at line boundaries if possible. cannot be combined with -update. performance notes the operating system may cache output files, writing to disk in background after sfk has finished. subsequent split commands may run slower, even if -noverify is used. examples sfk split 2g c:\bigfish.avi d:\transfer\ easy.avi splits bigfish.avi into easy.avi.part1, .part2 etc. to rejoin the files, use the sfk join command: sfk join d:\transfer\easy.avi.part1 e:\ full.avi joins easy.avi.part1, .part2 etc. into full.avi splitting text files by no. of lines: this is not yet supported by sfk, but for example the cygwin split command supports this. cygwin is a large package of commands, requiring some installation. if you have it installed, type for example split --lines=10000 biginput.txt outprefix which creates output files outprefixaa, outprefixab etc. see also: sfk partcopy copy a single byte block from a binary file sfk hexdump dump parts of a file for further analysis sfk snapto joins all text files of a directory you are viewing this page in mobile portrait mode with a limited layout. turn your device right, use a desktop browser or buy the sfk e-book for improved reading. sfk is a free open-source tool, running instantly without installation efforts. no DLL's, no registry changes - just get sfk.exe from the zip package and use it (binaries for windows, linux and mac are included).
