sorry as I may sound as an scratched music disk, but...
Irfanview can batch convert (also tga-->tga) while also in the proccess can make with the same touch of a button any operation you like from those I show you in bellow screens. It can even rename if wished.
Flip is among those batch operations.
Also even if u were to do one by one (weird if have many
![Wink ;)](./images/smilies/icon_wink.gif)
) irfan loads in no-time. Adobe takes a huge while... It has some batch support but very bad compared to Irfan's free tool .
Irfan's batch is just opening any file in the folder you have...like 20 tgas (1000) you want to batch convert/proccess....open the batch dialog ("File" menu or hit key "b") in irfan.
In that dialog, "ADD" all files. (or make a multiple files selection with shift and/or control keys, you can right click there and order your files by name, date, etc to make an easier selection.Or just select all with shift or something) Set the output directory (you have a button to set "same folder as outpu" which is really useful) .You can batch convert, batch rename, batch convert/proccess and renam in one, too.
For batch flip. Hit the advanced options button. Set the operations u want to happen always. (like flip.)
hit ok, hit in the main dialog "START" .If it gives the no error, no warnings message, you'd have converted and/or processed and/or renamed a bunch of files (or 2, 3, whatever)
It remembers your options as you left last time always, quite good.
Is really easy, and takes only some seconds, even if it's a load of images.
I know Trancos have already done a fix for you.
Is just I think this tool is simply essential.A pitty is windows only.
