Detecting activity within a specific folder

[simonic99]

Hi All

A little conundrum for you...

I already have AHK controlling my editing software to render a video file to a specific folder using my editing software. My challenge is to pause the script until the write completes and then allow it to carry on. I don't want to use an onscreen ImageSearch because that ties up my computer. Can anyone offer a way I can get the script to detect when the write process has ended?

Thanks.

Code: Select all

while(!FileExist("C:\my_render.mp4"))
	Sleep 25

assuming the rendered file appears only after its been rendered. also pause is a bit ambiguous. this snippet will merely delay it until then

OK thanks swag. I'd assumed the detection would be on creation. I'll give that a go.

Actually, just noticed, that doesn't solve my problem. I need a way to detect activity within a specified folder, but the file name is created on the fly, so I can't address that in the script.

Any other ideas or is this just not possible in AHK?

Maybe you could compare the folder size of the output folder.
At the beginning of your script you let it check the size
As soon as it has become bigger, you let your script continue.

I've never done something like that, though.
No idea if this can do the job.

How about this:

Code: Select all

While !FileOpen("outputfile.mp4","r-")
	Sleep 500
MsgBox Done rendering

Assuming the rendering software doesn't allow accessing the file by other processes while it's writing.

I haven't used it much but look at watchdirectory
