Here are a couple of methods to export the list of files in a directory into a CSV for analysis.

1. Powershell (Wrapped for use in CMD.exe)

The following command is a wrapped Powershell script that will run from a cmd.exe window.

powershell -Command "Get-ChildItem -Path . -File | Select-Object Name,@{Name='SizeBytes';Expression={$_.Length}},@{Name='LastModified';Expression={$_.LastWriteTime}} | Export-Csv -Path '.\file_list.csv' -NoTypeInformation"

Output:

• Name: File name
• SizeBytes: File size in bytes
• LastModified: Timestamp of the last modification

2. Native CMD.exe Prompt

The following is a native command line that can be run from the cmd.exe prompt.

(for /R %f in (*) do @echo %~pf%~nxf) > file_list.csv

Or to export recursively through subfolders as well:

(for /R %f in (*) do @echo "%~nxf",%~zf,"%~tf") > file_list.csv

Explanation:

• %~nxf — filename with extension
• %~zf — file size in bytes
• %~tf — last modified date/time
• for /R — recursively processes all files in subdirectories
• Output is saved to file_list.csv in the current directory
