Comments:

Suppose there is file c:\One\Two\Three\Four\name.ext. It is required to rename it using names of parent directories of any level.

For the first level counting from the file to the root the Multi-Rename Tool (MRT) of Total Commander can provide, for example, the [P]-[N] mask that yields the Four-name.ext name. Here the minus character is used as a delimiter.

To insert the next (grand-parent) level directory name (Threename.ext) the [G][N] mask can be applied.

Unfortunately, MRT can't use names of grand-grand-parent and higher, though the filex plugin and its function GtGrandPaDir can make up this deficiency: mask [=filex.GtGrandPaDir]$[N] renames file to Two$name.ext.

But even the filex plugin is not able to move upwards in the directory hierarchy. For these purposes the present script can be easily used.

Its first parameter is always "%L". Second one is a template. It contains numbers where each number corresponds to the level of ancestor. As it was said above, the current directory is considered to be level 1, parent - level 2, etc. Third parameter is an optional delimiter.

Script with the ("%L", "13", "%%") parameters renames the file to "Four%Two%name.ext" in the same directory (the percent sign must be specified twice). Another example: ("%L", "243", "-") parameters correspond to "Three-One-Two-name.ext".
