#Different ways to copy

#Copying Directories: Cheatsheet

#Initial folder structure

source/
  file1.txt
  file2.txt
dist/   # may or may not exist

#1. Copy folder to new location (target does not exist)

# dist does NOT exist
Copy-Item source dist
# Result:
dist/
  file1.txt
  file2.txt

#2. Copy folder into existing folder

# dist exists
Copy-Item source dist
# Result:
dist/
  source/
    file1.txt
    file2.txt

#3. Trailing slash behavior

Copy-Item source dist/   # same as Copy-Item source dist
Copy-Item source/ dist   # same as Copy-Item source dist
# On Windows, trailing slashes are ignored

#4. Copy only contents (not folder itself)

Copy-Item source\* dist -Recurse
# Result: dist/ contains files from source/, not source/ itself
dist/
  file1.txt
  file2.txt

Summary:

  • Trailing slashes on paths are ignored on Windows.
  • If target exists, source is copied inside it; if not, source is copied and renamed to target.
  • Use source\* to copy only contents, not the folder itself.
