- ARCE Command
- ------------
-
- Purpose: To extract files from an ARC archive file.
-
- Format: ARCE [d:][path]filename.ext [filespecs...] [d:outpath] [/R]
-
- Remarks: The drive and path names are optional. If omitted, the
- current drive and path name is used.
-
- The filename must be supplied. The extension defaults
- to ARC. All files matching the supplied filename are
- processed. The ARC filename may contain the * and ?
- wildcard characters.
-
- If no filespecs are supplied, all files are extracted.
- Otherwise, only those ARC members which match one of the
- up to 16 filespecs are extracted.
-
- The extracted files may be placed on another drive, and/or
- in another subdirectory by following the optional filespecs
- with a drive designator and/or path name.
-
- If the file being extracted already exists, you are asked
- whether or not you want to over-write it. You may use the
- /R option to bypass this prompt.
-
-
- Examples:
- --------
-
- o Extract all file from TEST.ARC onto the current drive:
-
- ARCE TEST
-
- o Extract only file with an extension of .ASM from the
- archive SOURCE.ARC on drive B and in subdirectory SAVE:
-
- ARCE B:\SAVE\SOURCE *.ASM
-
- o Extract all files from all ARC files in the subdirectory
- called TEST on drive C:
-
- ARCE C:\TEST\*
-
- o Extract all files from PROGA.ARC and place the files in
- subdirectory OLD on drive B:
-
- ARCE PROGA.ARC B:\OLD
-
- o Extract all files with an extension of .COM and .EXE from
- the archive PROGS.ARC in directory NEW\WORK on drive B,
- and place the them in subdirectory SAVE\TEST on drive A;
- replace existing file:
-
- ARCE B:\NEW\WORK\PROGS *.COM *.EXE A:\SAVE\TEST /R
-
-
- Error Messages:
- --------------
-
- 'filename - premature EOF reading '
- Data is missing from the archive file.
- The program is terminated.
-
-
- 'filename - unable to set file datestamp'
- The file datestamp is set to the current date and time,
- and the next archive member is processed.
-
-
- 'filename - WARNING: file CRC does not match!'
- The extracted member is left on the output disk,
- and the next archive member is processed. The file
- is probably invalid but is left on the disk for
- your examination.
-
-
- 'Invalid filespec(s)'
- The filespec syntax is incorrect. The filename part may
- be from 1 to eight characters, and may include the ? or *
- wildcard characters. The extension may be none to three
- characters, and may include wildcards.
- There is a maximum of 16 filespecs allowed.
- The program terminates.
-
-
- 'filename - file already exists. Overwrite it? (y/N) '
- The member being extracted already exists. If you are
- using a data path utility, the file may not actually be
- in the subdirectory be used for output. Respond with the
- letter Y to over-write the existing file, or respond with
- the letter N to skip this member and continue to the next.
-
-
- 'Abort: Stack overflow'
- The member being extracted has invalid data. The program
- is terminated.
-
-
- 'filename - invalid decode tree count'
- The member being extracted has invalid data. The program
- is terminated.
-
-
- 'filename - new archive format 7 not yet supported'
- Format 7 is a special file compression method used
- internally by SEA, the authors of ARC. Processing
- continues with the next archive member.
-
-
- 'Unable to open archive > arcname'
- The specified ARC archive file was not found, or was
- inaccesible. The program terminates.
-
-
- 'CREATE failed > filename'
- There was insufficient directory space, or a failure
- accessing the output disk. The program terminates.
-
-
- 'Invalid archive format!'
- The archive file data is invalid. The program terminates.
-
-
- 'Incorrect DOS version'
- Version 2.0 or later of PC DOS must be used. The program
- terminates
-
-
- 'Not enough memory.'
- A minimum of 112k bytes of memory is required. The program
- terminates.
-
-
- 'I/O error reading from arcname'
- An incorrectable error occurred attempting to read data
- from the archive file. The program terminates.
-
-
- 'I/O error writing or disk full > filename'
- There was not enough disk space to write the complete
- archive member. The partially extracted file is scratched
- and the program terminates.
-
-
- 'No matching file(s) found'
- No archive files were found that matched the supplied
- filename specifications. The program terminates.
