Is that really the sequence you want? I don't use Google Drive much, but in most cases, Select All followed by Delete will delete everything...is that not the case with Google Drive? 
 
Some comments on the code you posted: 
 
(1) It's a good idea to put code in a code block (the &quot;Style Code&quot; icon on the formatting toolbar). 
 
(2) Your step 3 says &quot;wait 3 seconds&quot; but your Sleep command waits for 5. 
 
(3) Your step 4 says &quot;loop for a 1000 times&quot; but your Loop command loops 10000 times. 
 
(4) The JCloop line is wrong. Remove it. The ^j:: line is correct and will result in the hotkey being Ctrl+j. 
 
(5) Use SendInput instead of Send. It is faster and more reliable. Alternatively, put SendMode Input at the top of the script and that will result in using the SendInput method for all Send commands. 
 
(6) Indentation is very helpful in code...makes it much easier to visualize the flow of control. 
 
Taking everything above into account, here's a better posting of your code: 
 

<pre><code class="code-1 nolinks" id="code-20-43284062-1">^j:: ; hotkey is Ctrl+j
SendInput,^a ; send Ctrl+a (SendInput is faster and more reliable)
Loop,1000 ; this is 1,000 times, not 10,000
{
 Sleep,5000 ; this is 5 seconds, not 3
 SendInput,{Del}
}
Return
</code></pre>
Note that the Delete does not occur immediately after the Select All, which the steps in your original post indicate. Rather, it occurs inside the loop, i.e., after step 4. 
 
That said, I don't know if this will do what you want in Google Drive, due to my lack of experience with it. Regards, Joe

It runs the first time, but doesn't run again. It selects all, then deletes once. Nothing else after that. I can run control + A then delete manually, or rerun the script with control+ J (It works once) <a href="https://drive.google.com/drive/my-drive" rel="ugc">https//drive.google.com/drive/my-drive</a>
</div>

<div>
Let's see if the loop is running more than once by putting a MsgBox inside the loop, and let's experiment with a small number of iterations (will create a variable for the loop count so it's easy to play with). Try this: 
 

<pre><code class="code-10 nolinks" id="code-20-43284076-1">^j:: ; hotkey is Ctrl+j
Count:=3
SendInput,^a ; send Ctrl+a (SendInput is faster and more reliable)
Loop,%Count%
{
 MsgBox,4096,Debugging,Loop iteration: %A_Index%
 Sleep,5000 ; this is 5 seconds, not 3
 SendInput,{Del}
}
Return
</code></pre>
Do you get three MsgBox displays with the iteration showing from 1 to 3?
</div>

<div>
I take that back. When I run the script, it runs fine the first time. Then control + A does not run. If I click on a file, it deletes it. It looks like the Del key is not working. If I press control + A manually or select a single file, it deletes it. 
</div>

<div>
<blockquote>

</blockquote>
Keep in mind that Ctrl+a is NOT inside the loop. Do you want it inside? I was assuming that you had it outside the loop because Google Drive keeps the remaining files selected after the Delete, but if that's not the case, you'll need it inside the loop.
</div>

<div>
I says loop iteration 1, 2, 3 Control + A only runs once though. The reason I know is that it puts 50 files in trash the first time. Nothing else is selected or put in trash. 
</div>

<div>
That was it, the ctrl + a needed to be inside the loop. You're the man Joe, thank you very much. Have a great day !

You're very welcome. I'm glad that did it for you. You have a great day, too. Regards, Joe

Autohotkey keyboard macro help

Windows Macro

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.

AutoHotkey is a free, open-source custom scripting language for Microsoft Windows, initially aimed at providing easy keyboard shortcuts or hotkeys, fast macro-creation and software automation that allows users of most levels of computer skill to automate repetitive tasks in any Windows application.
