- FDUP program and manual copyright(c) 1990-1994 by Ray Van Tassle.
-
- Abstract:
- ---------
- FDUP will find files with duplicate names on your disk(s). It
- works in conjunction with WIZ, which does the actual scanning of the
- disk(s).
- FDUP is just the thing for today's huge multi-gigabyte hard disks--
- it can handle over 123,000 files!! And fast---time to process
- (excluding printout time) 65,000 files is only 25 seconds on a 486/33.
- By default, FDUP will ignore some common filenames.
-
-
- Quickstart
- ----------
- You MUST have WIZ installed, and on the PATH.
- To get a list of all the duplicated filenames on your disks:
- >FDUP
-
- To consider only some of your disks:
- >FDUP CD:
-
- To get summary information, but not the actual filenames:
- >FDUP -q
-
-
- Operation & Versions
- --------------------
- * By default, FDUP will ignore these common filenames:
- DESC.SDI
- DESCRIPT.ION
- FILE_ID.DIZ
- READ.ME
- README.
- README.1ST
- README.COM
- README.DOC
- README.EXE
- README.TXT
- MAKEFILE.
- MAKEFILE.BAK
- WHATS.NEW
-
- * There are two executable files provided, FDUP.EXE and
- FDUP32.EXE. FDUP.EXE will run on any 80x6 PC. It will page the
- internal data-base to XMS or disk when it runs out of low DOS
- memory. Operation will slow down considerably once it starts
- paging. FDUP32.EXE runs in 32-bit protected mode, and will run
- only on a 386 or above. It uses the free GJGPP C compiler and
- GO32 DOS extender. It will use all available memory (low DOS
- and extended memory), and is *much* faster than FDUP.EXE paging.
- It seems to be always slightly faster than FDUP.
- If you have a 386 or above, I recommend that you delete FDUP.EXE
- and rename FDUP32.EXE to FDUP.EXE.
-
- * FDUP spawns WIZ to scan the disk(s). WIZ creates a temporary file
- (WIZDUP.TMP), which FDUP reads, then deletes.
- You can use any of the WIZ scanning rules, by placing the
- switches for WIZ in quotes:
- FDUP "*.exe -s10000"
- Will tell you about duplicated EXE files that are
- larger than 10KB.
- You *must* have at least one colon (:) or space inside the
- quotes, or it won't be recognized as parameters for WIZ.
-
-
- Command-line Switches
- ---------------------
- fdup [-dinqv] [disks-to-scan:] ["parameters for WIZ"]
- -d = Use disk for swapfile, not XMS.
- -i = Show only files identical by size.
- -ii = Show only identical files (CRCs match).
- -n = Display names only, not paths.
- -q = quiet--don't print dup's, just summary information.
- -v = (debug) print paging info.
- -vv = (debug) print files while reading.
-
- Disks-to-scan:
- * Omit to scan all disks (as defined by WIZ)
- * A list of disks, such as: "CDFG:"
- * A range of disks, such as: "C-J:"
- * A mixture, such as: "C-JWZ:"
- The ":" is required.
-
- Other specifiers:
- You can limit the search to particular filenames like this:
- >FDUP s*.exe
- >FDUP cd:foo*.dat
- >FDUP cd: *bar.*
-
- Notes on mixing parameters:
- >FDUP c: "-x " ---- allowed
- >FDUP "c: -x" ---- allowed
- >FDUP "c: -x " ---- allowed
- >FDUP c: "-x" ---- won't work
- >FDUP c: -x ---- won't work
- >FDUP c: "d: -x" ---- won't work right
- >FDUP "cd: -x" ---- do this instead
- >FDUP cd: " -x" ---- ... or this
-
-
-
- Upcoming features
- -----------------
- I don't know.
- Any request for showing the names of files which
- have exactly 'n' copies (including 1, for filenames which don't
- have duplicates)?
