Babcock > How awkward. My BBS has only a 20MB hard disk...... Gzipped tar files are generally about 80% the size of the corresponding zip files. But tar is not (?) available on MSDOS. What may not be widely known is that zip at zero compression is an excellent archiver. The corresponding gzipped files are a few hundred bytes smaller than their taz counterparts. I keep the pair of batch files which follow, on hand for serious file stuffing. - - - - - GZIP_DIR.BAT - - - - - REM Usage: GZIP_DIR TREE ARCHIVE, where TREE is the directory at the REM top of the structure and ARCHIVE is the name of the resulting file. REM The working directory should have TREE as a subdirectory. @ECHO OFF path_1\ZIP -oqr0 %2 %1 path_2\GZIP -8 %2.zip GOTO end Copyright notices, command summaries, options and any text so long as the total length of GZIP_DIR.BAT does not exceed the cluster size. :end - - - - - GUNZ_DIR.BAT - - - - - REM Usage: GUNZ_DIR ARCHIVE, where ARCHIVE.ZIZ is the compressed REM archive file. The files will be placed in their correct subdirectories REM if ARCHIVE.ZIZ is placed at the root of the intended directory tree. @ECHO OFF path_2\GZIP.EXE -d -q %1.ziz path_1\UNZIP.EXE -u %1 GOTO end Copyright notices, command summaries, options and lots of text so long as the total length of GUNZ_DIR.BAT does not exceed the cluster size. :end - - - - Frank Donahoe, Emeritus - Physics fdonahoe AT wilkes1 DOT wilkes DOT edu Wilkes University, Box 111 717-675-2493 (H) Wilkes-Barre, PA 18766 717-675-6567 (fax) USA `Haste makes entropy!'
