Volume compression under linux, downloaded from the file to the local Linux larger than 4G, and incorporated in the local

Background: Since when downloading files from the linux if more than 4G, use sz command can not be downloaded, so it is necessary to file volume compression.

step:

　　1, large files will be compressed into a 1G file: cat mydata.zip | split -b 1G - mydata_20200302.zip. 

　　　　Which mydata.zip large file name, mydata_20200302.zip. This split is the prefix for the file, the default file name after the spin-off is mydata_20200302.zip.aa, ab, ac .... and so on　　　　

　　　　

  　　2, each compressed file to download to a local 2G: sz mydata_20200302.zip.a *

　　　　

  　　　 

  　　3, these compressed files into a compressed file, open cmd input:　　　　

　　　　copy / B mydata_20200302.zip.aa + mydata_20200302.zip.ab new_mydata.zip,
　　　　this time will be in the current directory new_mydata.zip generated, is the last file to be decompressed.

　　　　

 

 　   　

  　　4, the last 360 decompression tool you can use unpack it!
