Clone, Synchronize, and Refresh Directory Commands in Laplink V/DOS

Document relates to: Laplink for DOS



What are the differences between the Clone, Synchronize, and Refresh Directory commands?



Below are explanations and examples of the Clone, Synchronize, and Refresh Directory commands. 

NOTE: They all have built-in copy options that are used to perform their specific functions. Therefore, the file-specific Copy Options in Laplink V/DOS are not in effect when using them.


The Clone Directory makes the contents in the target directory identical to the source. (The source directory is the one the highlight bar is in when the command is used.) It is a destructive copy and will delete files in the target directory that do not exist in the source. (The target directory is the one that is open on the opposite side of the highlight bar.) Files with the same name in each directory are compared by date and time. If the source file has the newer date and time, it replaces the target file without a prompt. If the target file has a newer date and time, a prompt appears asking whether or not to overwrite the target file.

Clone Directory is useful when the target directory contains data files you want to delete. For example, many people delete files in a directory that they no longer need. If these deleted files were previously copied to the target directory, they will still exist in the target machine after copying new and updated files to this same directory. With Clone Directory however, these files are deleted in the target since they don't exist in the source. This produces a consistent organization of the data and reduces storage space on the target drive.


The Synchronize Directory is a two-way process that copies newer and unique files between two directories and makes them identical. It does NOT merge the contents of two files to make the files identical. If two files are found with the same name, the file with the older date and time is replaced (overwritten) with the newer file.

Synchronize Directory is useful when the two directories contain different data that you want to interchange between the two. For example, if you create different data files with two different machines, you can quickly update each machine to contain the other's data.


The Refresh Directory is a one-way copy that only copies existing and newer files from the source to the target directory.

Refresh Directory is useful when you want to copy data files you've recently worked with and have already copied to the target directory. For example, you always work with the same data files of a particular application and want to keep a backup of these files. After initially copying these files to the target, Refresh Directory will quickly update the target by only copying the updated files that already exist in the target directory.

NOTE: All of these commands will all work at the root drive level as well as the directory level. We recommend using these commands ONLY at the directory level. For example, to check the directory level:

After establishing a connection, view the bottom left-hand corner of both sides of the screen and be sure a directory name appears. The directory levels should read Remote: (or Localsmile C:\directory_name not Remote: (or Localsmile C:\ .
