AWS S3 Downloader

Why this package?

• This package is intended to be used when you want to download files from S3 to a Windows machine but the file names contain reserved characters and so, neither the AWS CLI nor the available AWS SDKs download the files. Have a look at this issue: Issue with downloading s3 objects on Windows

• Do not upload the files and folders back to S3 after downloading them using this package since the uploaded files will have different names and will exist side-by-side along with the original files (unless you are sure of what you are doing).

What this package does

• This package downloads all the objects in a specified S3 bucket into a local directory.
• While downloading the files, the script replaces reserved characters in the filename for Windows with dashes (-) to prevent issues.
• It converts the following reserved characters:

    < (less than)
    > (greater than)
    : (colon)
    " (double quote)
    / (forward slash)
    \ (backslash)
    | (vertical bar or pipe)
    ? (question mark)
    * (asterisk)
    \x00 (ASCII NUL)

• The reserved characters are based on Naming Files, Paths, and Namespaces
