Question

I have to convert my game’s texture files to ETC (Ericsson Texture Compression) format,
using the command line conversion

etcpack img.jpg new-img.jpg

I have 100+ files in a the folder and using the etcpack tool on each file from command line is a pain.

Can i write a dos script or batch file to do that and how should i do it for all files in my current folder and subfolders.

Answer 1

From the command line, without using a script:

for /r %F in (*.jpg) do etcpack "%F" "new-%f"

You shouldn’t run the above command twice, else it will try to convert the already converted “new-…” files. The following more complex command is safe to run multiple times.

for /f "eol=: delims=" %F in ('dir /b /s /a-d *.jpg ^| findstr /vlib "new-"') do etcpack "%F" "new-%F"

If you want to put either command in a batch script, then change each %F into %%F.
