You can get the gzip (gzip.exe) command line utility from the gzip home page . Thanks to Mark Adler and Jean-loup Gailly . http://www.gzip.org/ You could then try this ... ECHO OFF FOR %%f IN (C:folder*.cr2) DO C:foldergzip.exe -l %%f SUF .crz %%f > C:foldergzipFileInfo.txt FOR %%f IN (C:folder*.pz2) DO C:foldergzip.exe -l %%f SUF .p2z %%f >> C:foldergzipFileInfo.txt ECHO ON copy into notepad, rename as gzip.bat, and double click it . it basically looks for cr2 files in C:folder, converts them, using gzip.exe in C:folder into crz files . -l switch lists the info and > prints the stdout (screen output) to gzipFileInfo.txt . And does the same for the pz2 files, except >> appends the .pz2 info to the same text file .
