[ Usage description ]

key input :
 Push "c" key if you want to cancel process.
 Push "p" / "r" key if you want to pasue / resume process.

exit code (bit-wise OR) :
  0 = normal end
  1 = fatal error
  2 = cancel by c-key
  4 = input files are incomplete
  8 | 4 = need more blocks to repair
 16 = repair succeeded
 16 | 4 = repair failed
 32 | 4 = rename, move, and/or restore is possible
128 | 4 = repair is possible
256 = PAR files are incomplete

specifying <par file> :
 <par file> is either absolute path or relative path from current directory.
Note, it is not relative path from the PAR client's directory.

create :
 You create PAR recovery files.
To specify PAR files, <par file> cannot contain "*" or "?".
If you create multiple PAR files like "sample.par, sample.p01, sample.p02",
set base filename. Normaly it is same as filename of index file. (sample.par)
The default extension (.par) is appended automatically, unless it exists.

 You can write multiple input files in command line.
The order of files in a recovery set is different from this command order.
You cannot supply input files of same filename as the creating PAR files.

 All input files must have same base-directory (root).
This directory can be set by /d option, or directory of <par file> is used.
Though it is possible to input with absolute path,
[input files] are set as relative path from the base-directory.
A short filename in a path will be converted to long filename.

 [input files] can contain "*" or "?" for search.
"*" is treated as multiple unknown characters.
"?" is treated as single unknown character.
If it is "*", all files in the specified directory are searched.
If these are "*.txt" and "*.doc", files with extensions ".txt" and ".doc"
in the specified directory are searched.
When you don't see hidden files on Windows Explorer, they are ignored by search.
If you want to search hidden files, change Windows Explorer setting to see them.

verify :
 You check files in a recovery set.
If some files are damaged or missing, this show how many slices are available.

 If you have multiple PAR files, specifying whichever filename is possible,
but setting base filename (or filename of the smallest file) is preferable,
because the selected file is scanned at first.
For when the specified PAR file does not exist,
<par file> may contain "*" or "?" with partial filename to search another PAR file.

repair :
 You check and reapir files in a recovery set.
If you want to check only, use verify command.

list :
 You see what files are included in a recovery set.
This does not check files, so run very fast.


[ Option description ]

 Every options must start with prefix "/" or "-".
If you use either one at first option, you must use it at all following options.
It means that it is impossible to mix "/" and "-" in options of same command line.
If PAR file's filename (or relative path) is started by "-",
you need to use "/" for prefix of options to distinguish PAR file.

 When a option has arbitary number or text,
don't put space between the option and following part.
For example, setting "/rr1" is valid, but "/rr 1" is wrong.
Setting "/dPath" is valid, but "/d Path" is wrong.

 To distinguish options from filenames, order of command-line arguments is important.
Put all options before <par file>.
Put <par file> before all [input files].


 /f, /fu :
 Set this, if you use file-list for file name or file path.
The file-list is a text file, which contains filenames in each line.
If you encode filename in the list by UTF-8, set /fu instead of /f.

 /r :
 Redundancy can be from 1% to 127%.
If this is not set, /n is used.

 for example,  /r10 , /r30 , /r100

 /n :
 Set number of parity volumes directly.
If this is set, /r is ignored.
If both /r and /n are not set, parity volume is not made.

 for example,  /n3 , /n10 , /n20

 /p :
 Set first number of parity volume.
For example, when 10 parity volumes are on creating,
the number of created parity volumes are from 10 to 19 for /p10,
and from 64 to 73 for /p64.
Default is 1, then from 1 to 10.

 /m :
 Set this, if you want to set memory usage.
If too many memory is allocated, system will use swap file.
Because swap causes serious speed down, limiting memory usage may useful.
The value is from 1 to 7. (from 1/8 to 7/8)
It is a rate against the PC's available physical memory. (not total memory)
If this is not set or the value is 0, the rate depends on free memory.
/m0 = Auto is default (between 6/8 and 7/8 mostly)
/m1 = 1/8, 12.5%
/m4 = 4/8, 50%
/m7 = 7/8, 87.5%

 /vs :
 Set this, if you want to save a current verification result
and/or re-use a previous verification results.
This feature is disabled by default. (same as /vs0)
If you want to disable this feature, set 0.
If you want to re-use a result of recent verification, set value from 1 to 7.
Old data files are erased, when there is no update for the specified period.
(1= 1 day, 2= 3 days, 3= 1 week, 4= half month, 5= 1 month, 6= 1 year, 7= unlimited)
If you want to newly create a result of this time, add 8 to period.

 One recent verification result data is saved as one file, "1_***.bin".
*** part depends on Recovery Set ID.
Don't modify these files, or corrupted data will make failure.

 /vd :
 If you want to save recent verification results in a different directory
from the PAR client's directory, use this setting to set path.

 /c :
 Comment may be useful for memo ?
If you include space in comment, use "" to specify where is end.

 for example, /csomething , /c"something important data."

 /d :
 If input files exist in a different directory from PAR file,
use this setting to set the path as base-directory.
This is either absolute path or relative path from current directory.
If you include space in path, use "" to specify where is end.
As you may omit the last "/" in path of a folder,
both "/dC:/data/" and "/dC:/data" are valid.
Note, setting "/dD:" is same as setting current directory of D-drive.
If you want to set direct root of D-drive, you must set "/dD:/".

 for example, /dC:/data/ , /d"C:/Program Files/" , /d../data/

 When this is not set, the directory of PAR file is used.
If input files are specified with absolute path in command-line,
the parent directory of the first input file is used.

 If damaged files exist in read-only media like CR-ROM or DVD-ROM,
copy all files to HDD at first, then repair those damaged files.

 /i :
 Set this, if you want to recreate a lost Index File while verification.
This option is ignored, when there is an Index File already.

 /in :
 Set this, if do not you want to create an Index File.

 /u :
 This setting is useful to show filename of non-supported language.
You may decode the UTF-8 encoded output with Internet Browser.

 /b :
 If you want to make backup at repair, set this.
This is important setting, because this application may contain bugs.
The existing damaged file is renamed by adding number extension like ".1" or ".2".

 /br :
 This is almost same as /b option.
The backup file is sent to recycle bin instead of the original directory.
When path of a damaged file is too long, this works as same as /b above.

 /h :
 If you want to see hash of files in recovery file, use this.
You can compare yourself with other hash checking soft.
