I have a lot of files. Can I do a batch upload, rather than one at a time?
[edit]cut/paste from Commons:FAQ 12:43, 5 July 2011 (UTC)
- Yes. The Commonist is a Java/BeanShell-based upload tool with a graphical user interface. It reportedly works well under Linux and MacOS, and should work on Windows too (although some people have reported problems under Windows).
- For those comfortable with the Unix command line, a script by User:Nichalp, based on Eloquence's file upload script in Perl is suitable for most Unix, Unix-like, Linux or Mac OS X machines.
