copy_files_to_target_dir: Copy Files to Flat Structure

In KWB-R/kwb.file: Functions Related to File and Path Operations

Description

Calls file.copy under the hood but gives a message about the indices and paths of the files that could not be copied.

Usage

copy_files_to_target_dir(from_paths, target_dir, target_files)

Arguments

from_paths	paths to the files to be copied
target_dir	path to the target directory
target_files	relative paths to the target files, relative to target_dir

Examples

root <- system.file(package = "kwb.file")

relative_paths <- dir(root, recursive = TRUE)

# The original files are in root or in different subfolders
relative_paths

# Create a temporary target folder
target_dir <- kwb.utils::createDirectory(file.path(tempdir(), "target"))

# Copy all files into one target folder without subfolders
from_paths <- file.path(root, relative_paths)
to_paths <- basename(from_paths)

# Make sure that the target file names contain no duplicates, otherwise
# an error is raised
to_paths <- kwb.utils::makeUnique(to_paths, warn = FALSE)

# Copy the files
copy_files_to_target_dir(from_paths, target_dir, to_paths)

# Look at the result
dir(target_dir, recursive = TRUE)
