Thanks for the help..
I am sorry it took me so long to respond... I have not been well, so I have not been at the computer in a while.

I have a list of file names in a text file. Since the files come from multiple sources including the internet, some have valid extensions, some do not. The question is... How do I check if a file extension is valid? At first glance, I thought that if SplitPath provided a 3 character extension, chanc...

I tried your function... Perhaps because it was inside a nested file loop, it got stuck. Apparently there was an issue with the while InStr. I am uncertain of what the loop in your function was for, and I was equally uncertain of what the SplitPath was for, so I did some trimmng. The result I arrive...

@Noesis: Thank you very much for that! Since jeeswg asked it there was a way around this problem, I have been playing with trying to use the command prompt to identify the links, (which it can do) and use that information to influence the loop. Your solution is far superior! I know that dll's have b...

@just me....
That is very interesting. Thanks for the information.

I am not sure if there is a way to exclude the links (the name of the alternative references to the same file/folder) directly. However, it does not effect me personally much because I don't cycle through an entire drive as I have done for the demonstration purpose here very often. One thing that I ...

Well, I have no idea how the functions are implemented, so I can't say what conversions are being made behind the scenes. However, a quick and dirty test (ie, not a specifically controlled enviroment for testing) suggests that other variables, ie. FileSize and Date are equally as quick as the A_Loop...

I will ask in advance for forgiveness if this is not actually a bug, and should have been put elsewhere.... I was really unsure where to put it. Apparently, the use of A_LoopFileLongPath in File Loops is Orders of Magnitude slower than using other File Loop variables... Here is the test code I used,...

Doh!

I forgot to paste the actual code... Corrected with edit

Yes, it uses the format time function...

This just makes it easier to use in an expression...

YMD(Date)

Converts a date from YYYYMMDDHH24MISS to YYYY-MM-DD

If Date is left blank, it converts the current date

ex... x=YMD()

if A_Now is 20140513092817 then the value of x as a string is 2014-05-13

YMD(DDate:="")
{
FormatTime, YMD, %DDate%, yyyy-MM-dd
return (YMD)
}

The above doc will tell you precisely how to set up a F hotkey... after that, setting up the action is the same as with any other hotkey.

Hi Wan...

I just emptied C:\Windows\Prefetch\ (the only prefetch I could find on C) and it had no effect.

As near as I can tell, the F-keys are just another key as far as AHK is concerned.
