powershell - how to rename files to sub directories using cmd -


i have several levels of folders , these folders contain *.csv files. need rename these files in next format:

source sub-directories files:

c:\folder1\folder2\filename1.csv c:\folder1\folder2\filename2.csv ...

output:

c:\folder1\folder2\folder1_folder2_filename1.csv c:\folder1\folder2\folder1_folder2_filename2.csv ...

could this?

thanks

your questions says "using cmd" you've tagged powershell. think people assume want powershell answer rather script work in old-style nt command prompt...

get-childitem build list of files under folder, maybe folder1 in case. can filter files ending in ".csv" , move recursively through sub-folders using -recurse switch.

$source_files = get-childitem *.csv -file -recurse

the $source_files variable include list of files. need loop through list (hint: use foreach) , perform following:

  1. get full name of directory file in
  2. split array divided "\" character
  3. join array again using underscore character
  4. rename file folder names @ front

list others have commented, we're not going write script, people happy people new powershell going in right direction. remember research can!

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
