If the do so the processed file have to be updated.Īnother idea would be to only process files which ware larger (in kb) than a given level. append the path and filename to processed.txtīut with this solution your users shouldn't be allowed to rename or move files or directories. if so, skip this file, and process the next for all files in toprocess.txt check if the file and path is in processed.txt first scan for all jpegs and store the file list in a text file like toprocess.txt So saving your file.txt would be a good idea. What you need is a tool or a script which will generate a list with the currently unproccesed files. I guess you will soon find out if there is.īut if you repeat this batch for all the images once again, all the images you resized before will be resized again. I do not know if there is a limit to the length of list that Irfanview can handle. In the Batch dialog you can either load your existing file list by pressing the Load TXT button, or you can check Include subdirectories and let Irfanview find all the files in the sub-folders.
You must actually Save the jpeg file for the settings to be stored, so make sure that it is a file that you do not mind the quality being changed. Open the Save Options if not already displayed and set quality to 70. To set that you need to open a jpeg file in the Viewer, press File >Save As. You cannot set the jpeg quality in the Advanced batch dialog - it uses whatever setting is stored in the Jpeg Save options. The Create subdirectories option in the Advanced options does the job for you. Note that you leave the Outut directory box blank. I have attached an image of the settings you will need. It'll be a huge pain to have to do two steps! If I can just start it on a machine and let it run overnight, it'd be really beneficial. What's up with that? Anyways to get around this with the right fields selected? I've got 3 servers with thousands of folders with hundreds of JPGs. If I select "batch conversion - rename result files" its grays out the Batch Rename Options to rename the original. The issue I have when trying to do it with the GUI is that unless I do two steps (one convert and one rename) then I end up with still having the original and the new renamed copy. Once I figured out that it would find the files in subfolders, I realized that I didn't HAVE to do it from command prompt (although it'd be cooler). On another note but same topic, I'm trying to do the same thing with the GUI as a batch. How do I tell it overwrite the original files? The renaming is just so in the future we'll know that this file has already been changed. I want to change and rename the original. The things is, I don't want new files output. Yes directly from the command prompt but no error messages. the process just keeps running in the background.
It run's but it doesn't seem to be changing the files. It looks like this:Ĭ:\1tmp\pics\Joffrey\Pictures\2008\Finning BFP_5.JPGĬ:\1tmp\pics\Joffrey\Pictures\2008\Finning BFP_6.JPGĬ:\1tmp\pics\Joffrey\Pictures\2008\Finning BFP_7.JPG I'm doing dir *.jpg /b /s > jpglist.txt to get my list. What I need to do: find all the jpgs in a directory that has 100s of subfolders and then resize/quality and rename the file (append something to show it's been resized, like _rz) for each one. I've found that dropping the quality to 70% and resizing to 75% doesn't cause any quality loss but it reduces size by 90%. Employees upload images with whatever settings they were taken with. Upon analysis on each server, the thing taking up the most space is usually jpgs.

We have several storage servers that we're trying to free up space on. Here's the background so you'll understand what my goal is.
