- DCOPY
- Command
- ________________________________________________________________
-
- Purpose: Copy one or more files to the specified disk and path
- based on a comparison of file dates and passed date.
-
- Format: DCOPY [d:][path]filename[.ext] d:[path] [-][MM/DD/YY] [HH:MM:SS]
-
- Where: everything between the two braces "[" and "]"
- is optional and,
-
- d: - is any valid drive specifier
- path - is any valid path name
- .ext - is any valid file name extension
- - - is the before date indicator
- MM/DD/YY - is a valid date (month, day, year)
- HH:MM:SS - is a valid time (hours, minutes, sec)
-
- Remarks: This command functions in very much the same manner as
- the PC-DOS COPY command. However, DCOPY lets you copy
- files based on the file's creation date or update time
- stamp. There are two major differences between DCOPY
- and the PC DOS command COPY. First, files are copied
- to the specified drive and path ONLY if each file date
- and time is greater than, or less than, the time and
- date included in the command. Second, files can NOT be
- renamed as they are copied.
-
- DCOPY copies a file or group of files based on the file
- dates. Full wild card and path support are included.
- The global characters "?" and "*" can be used in in the
- file name and extension parameters. These global
- characters work in exactly the same way as they do with
- a COPY command.
-
- To use DCOPY you must specify a file name or pattern,
- and a destination drive at a minimum. If no date or
- time is included in the command, DCOPY assumes you want
- to copy all files created or updated on the current
- day. Thus:
-
- dcopy *.* a:
-
- copies all files created or updated after 12:00 AM on
- the current day. This assumes the time and date set in
- your IBM PC, XT, or AT is correct.
-
- Making a copy of files based on a different time and
- date is just as easy. To do this DCOPY needs to know
- the date and whether to copy files created before or
- after this date. The minus key is used to indicate
- whether you want to copy files before the specified
- date. You can optionally append a date and time to
-
-
- 1
-
-
-
-
-
-
-
-
-
- split the copy based on a specific time and date. Note
- that if no TIME is specified the time is assumed to be
- 0:00, the previous days midnight.
-
- dcopy *.* b: 12/12/84
-
- copies all files from the default drive with the
- extension ".obj" that were created or last updated ON
- OR AFTER 12 AM on 12/12/84 to the B: drive. The files
- copied to drive B: will have the same name and time
- stamp as they had on the default drive.
-
- dcopy b:work.* a: -1/2/85
-
- copies all files from the B: drive that have the file
- name "work" and any extension, to the A: drive PROVIDED
- that the file was last created or updated before 12 AM
- on 1/2/85.
-
- dcopy c:\work\*.c d:\help 2/20/86 15:00:00
-
- copies all files with the extension ".c" from the path
- c:\work to the path d:\help provided each file was last
- updated on or after 3:00 PM on 2/20/86.
-
- Problems: DCOPY can only handle directories that have less than
- 2048 matching file entries. If you hard disk has more
- than that number of entries try different file patterns
- to transfer less than 2048 files at a time. Instead of
- *.* use *.c and *.obj.

- DISTRIBUTION NOTICE
-
- This program is protected by United States Copyright law and
- by International Treaty provisions. You may distribute, or share
- the "demo" version of this program with anyone provided the
- following conditions are met:
-
- A "demo" version of DCOPY is being distributed at no charge to
- all who are interested in it. To those of you unfamiliar with
- this approach, it works like this. DCOPY is distributed to
- various BBS systems and user groups. You may copy the program
- and use it for no charge. Elfring Consulting, Inc. does not
- handle the actual freeware distribution of this program.
-
- The BBS version of this program has been INTENTIONALLY limited.
- First, it will only work until 9/1/86. Second, one major feature
- has been left out of this "demo" version of DCOPY. The real
- DCOPY checks the amount of disk space available on the destina-
- tion drive before each file is written. If there is not enough
- room DCOPY will pause and let you change disks. (The demo ver-
- sion does check the room but quits when the drive becomes full.)
-
- These limitations are imposed to be sure you pay for this program
- if you want to use it. Very few people seem to pay for the
- program otherwise. NOTE: that even though this version is lim-
- ited it is fully functional. Try the BBS version out. If the
- product does not meet your needs, you pay nothing. If the pro-
- duct does meet your needs, and you can use it, then send us a fee
- of $20.00. We will then supply you with the real version of
- DCOPY, (the missing features are enabled), along with printed
- documentation for that version.
-
- Send check or money order to: Elfring Consulting, Inc.

-
- Even if you do not contribute, you are encouraged to copy and
- distribute the BBS version of the product freely subject to the
- following restrictions:
-
- 1. Do not distribute altered copies. If you have suggestions or
- fixes you would like to see, send us a written note. We
- welcome all responses.
-
- 2. This product must be distributed complete including the files:
- DCOPY.EXE, and DCOPY.DOC.
-
- 3. No fee is to be charged for copying or distributing the pro-
- gram without an express WRITTEN agreement with Elfring
- Consulting, Inc. The ONLY exception to this rule is: a small
- charge, ($5 to $15), may be leveled if this program is in-
- cluded on a set of public domain disks. This charge must be
- reasonable and represent only copying and disk fees.
