Is there a way to find a or all files that have an Image Compression of LZW in File Browser in Photoshop?
What about Byte Order of IBM PC?

Thanks in advance

File Browser probably can’t. But simple shell scripts in Terminal can do it:

Listing IBM PC byte order files in current directory (watch out for spaces or other special characters in file names):

for f in * ; do

( dd if=$f bs=1 count=2 2>/dev/null | grep II >/dev/null ) && echo $f

done

If you install the libtiff <http://www.libtiff.org/> tools you can list LZW compressed TIFFs:

for f in * ; do

( /usr/local/bin/tiffinfo $f 2>/dev/null | grep LZW >/dev/null ) && echo $f

done

If anyone’s going to try the above, here is a way to install the libtiff tools:

First, download the source archive from this page <http://dl.maptools.org/dl/libtiff/>: click the Download button next to "tiff-v3.6.1.tar.gz".

Put that file in your home directory.

Open a new Terminal window.

Execute the following commands (return after each one):

tar -xzf tiff-v3.6.1.tar.gz

cd tiff-v3.6.1

./configure

(When prompted, accept the default configuration by typing yes and return)

make

sudo make install

(enter your password at the prompt)

Now the TIFF library and tools have been installed and can be accessed from Terminal as /usr/local/bin/toolname. More information here <http://libtiff.org/tools.html>. The archive and the directory tiff-v3.6.1 are no longer needed and can be removed if desired.
