chdkptp runs on windows 10 64 bit, and doesn't care about the edition. The multicam.lua script runs anywhere chdkptp does.

Is there a command I can use to erase all images on all the cards in a multiple camera array? I've been googling a lot and cant seem to find it in any form that I can understand... :-(

Use mc:imglist and mc:delete_files_list
See https://app.assembla.com/spaces/chdkptp/subversion/source/831/trunk/lua/multicam.lua#ln1104

so, to review for my noob brain, I run multicam and type exactly:

mc:imglist

Press Enter. Then type:

mc:delete_files_list

Press Enter. And then it's done?

mc:imglist

Press Enter. Then type:

mc:delete_files_list

Press Enter. And then it's done?
mc:imglist returns a list of files mc:delete_files_list deletes files listed in the same format.  So you'd want  something like
Code: [Select]
!mc:delete_files_list(mc:imglist())

The link was supposed to go to an example on line 1104, but apparently linking to specific line numbers no longer works on assembla >:(

Hi Guys

Is there a way I can set all 14 cameras in my multicam setup to download their files to one single central folder? They currently download into a CHDK folder, and create sub folders within subfolders. Having them all download to one single folder would make this setup MUCH easier. Looking forward to hearing your wisdom! Thank you :-)

Yes, but you need to ensure they end up with unique names. Two cameras could easily have files named IMG_0001.JPG. If you take many images between downloads, this could also happen on a single camera.

The download_images function accepts "substitution patterns" similar to the ones used by the imdl command in chdkptp. Use help imdl for information on that.

Download images adds a substition ${id} which is the number of the the camera.

The default download path (dst option to download images, see multicam.lua are around function mc:download_images) is
Code: [Select]
${id}/${subdir}/${name}
Which means a directory for the camera ID (e.g. 01,02 etc) the DCIM subdirectory from the camera (like 100CANON or 100___01 etc) followed by the image name (like IMG_0001.JPG)

If you just wanted to turn these into filenames without sudirectories, you could just swap the / to something else, like:
Code: [Select]
mc:download_images({dst='${id}_${subdir}_${name}'})
Then your files would be named like
01_100_01_IMG0001.JPG

edit:
If you want to download to somewhere other than the chdkptp directory, just put that at the start of the dst string, like
Code: [Select]
mc:download_images({dst='c:/pictures/${id}_${subdir}_${name}'})
You should use / instead of \ for directory names.

Thank you Reyalp. I've set each camera to be 300 digits apart from each other (Camera 1 = 0001, camera 2 = 0301, Camera 3 = 0601, etc). So as long as I dont take more than 300 images in one session and empty the download folder between sessions, this shouldn't be a problem.

Your option to just use the image names without subdirectories, paired with the ability to put them in a specific folder other than the chdkptp directory, would be the perfect solution.

Please forgive my noob brain, but do I just take the codes you've written, and enter them into CHDKPTP command line prompts? And if so, do I need to do it every time I start the program or just once? Thank you.
