Using pdftk what command can I use to join files, first in the order of the file that was created first?<br />
<br />
For example, let's say in the path C:\Attachment, there are 4 file all with different names, however all with different time stamps... <br />
<br />
How can I modify this command so that it joins each file it finds but based on time stamp? all into 1 file?<br />
<br />
pushd &quot;C:\Users\Desktop\Folder&quot;<br />
pdftk ….. cat output C:\Attachment\OneFile.pdf<br />

Join several pdf files based on time stamp

A Portable Document Format (PDF) is a file format consisting of an electronic image resembling a printed document and can be viewed, printed, and electronically transmitted. PDF files can store various types of data, including formatted text, vector graphics, and raster images. The page layout defines the location, size, and shape of each page and each item on the page. The information looks the same no matter what device or program is used to open it.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
