<h3>Common options</h3>
|
|
|
|
<dl><dt><b>
|
|
Log output of clients
|
|
</b></dt><dd> 
|
|
You can save command-line by GUI and output from the client.
|
|
This log is useful, when you get an error,
|
|
or if you want to use the PAR client on Command Prompt.
|
|
The log file is "<tt>MultiPar.log</tt>" in "<tt>save</tt>" folder.
|
|
The folder can be opened by double-clicking status text on Creating or Verify window.
|
|
If the log file becomes too large, next output is saved in another file "<tt>MultiPar.#.log</tt>".
|
|
When you don't need those log files anymore, delete them by yourself.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Clear log
|
|
</b></dt><dd> 
|
|
When you want to delete all log files at once, push this button.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Run clients with lower priority
|
|
</b></dt><dd> 
|
|
When the response of PC to your control becomes too slow, while MultiPar is running,
|
|
you may check this option.
|
|
This is useful to run MultiPar in background, while you do another task on the same PC.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Don't wait finish of other tasks
|
|
</b></dt><dd> 
|
|
Only when you want to run multiple instances' tasks at the same time,
|
|
check this option.
|
|
Because each creating or repairing task consumes PC resource exclusively,
|
|
total speed may happen to be slower than queued tasks.

<h3>Creation options</h3>
|
|
|
|
<dl><dt><b>
|
|
Format of recovery files
|
|
</b></dt><dd> 
|
|
You can change the version of newly creating PAR files.
|
|
You should use "<b>PAR 2.0</b>" normally.
|
|
You may use "<b>PAR 1.0</b>", only when source files are almost same size.
|
|
<!--You may use PAR 3.0 only when you are not satisfied with PAR 2.0 format.-->
|
|
<!--Currently "<b>PAR 3.0</b>" is available only for testing purpose of new technology.
|
|
If you want to test old sample PAR3 files,
|
|
you move "<tt>par3j_old.exe</tt>" from "<tt>tool</tt>" folder to the parent folder,
|
|
and rename it to "<tt>par3j.exe</tt>".-->
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Range of redundancy
|
|
</b></dt><dd> 
|
|
You can change the range of redundancy slider-bar on Create window.
|
|
This may be useful, if you want to set small or large redundancy mostly.
|
|
Even when the range is limited, you can set more redundancy by typing number of recovery blocks directly.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Always use folder name for base filename
|
|
</b></dt><dd> 
|
|
Unless you type the filename by yourself,
|
|
"Base Filename" is set automatically after you select source files at first.
|
|
The method of naming is same as QuickPar like;
|
|
(1) When there is only one source file, the filename is used.
|
|
(2) When there are multiple source files, the preceding common part of filenames is used.
|
|
(3) Else, the folder name of parent directory is used.
|
|
If you want to use the last naming method always,
|
|
check this option.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Don't search subfolders
|
|
</b></dt><dd> 
|
|
When a folder includes subfolders,
|
|
all files in each folder are searched recursively by default.
|
|
If you want to ignore subfolders, check this option.
|
|
Even when it's checked, you can add inner files manually.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Don't create index file
|
|
</b></dt><dd> 
|
|
Index file is the smallest PAR file, which does not contain any recovery blocks.
|
|
It is available to verify source files, but is useless to recover a damage.
|
|
If you don't need the file, check this option.

<h3>Verification and Repair options</h3>
|
|
|
|
<dl><dt><b>
|
|
Monitor files to verify
|
|
</b></dt><dd> 
|
|
If you check this option,
|
|
MultiPar will monitor recovery files and source files after the first verification.
|
|
When new files are added or some files are modified, they are verified automatically.
|
|
After when a previous verification was ended by error, all files were complete,
|
|
or all files were repaired successfully, monitoring will finish.
|
|
If you want to cancel monitoring at any time, push "<b>Escape-key</b>".
|
|
After that, you may click "Verify" button or push "F5-key" to start monitoring again.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Repair automatically
|
|
</b></dt><dd> 
|
|
If you check this option, MultiPar will start repair after verification if possible.
|
|
When this isn't checked, it does verification only.
|
|
If you are lazy to click "Repair" button everytime, this may be useful.
|
|
The setting is enabled for all verification by "F5-key", "Add", or "Monitor".
|
|
Even when some files might be restored, if it is impossible to repair all files,
|
|
it won't repair at all.
|
|
</dd></dl>

|
|
<a name="verification_level"></a>
|
|
<dl><dt><b>
|
|
Verification level
|
|
</b></dt><dd> 
|
|
Normally "<b>Detailed verification</b>" is good.
|
|
"<b>Simple verification</b>" is faster, when damage didn't delete or insert bytes.
|
|
"<b>Additional verification</b>" will check all files in the base directory.
|
|
When filenames of damaged files are different,
|
|
or when source files are contained in a non-compressed archive like ISO-image,
|
|
select "Additional verification" to add them automatically.
|
|
"<b>Aligned verification</b>" is the fastest, but it doesn't backup damaged files.
|
|
Because it will over-write damaged file directly, there is a risk of more data loss at failed recovery.
|
|
</dd></dl>
|
|
|
|
<a name="reuse_result"></a>
|
|
<dl><dt><b>
|
|
Re-use verification result
|
|
</b></dt><dd> 
|
|
If you want to skip some part of verification at next time, set some period in this option.
|
|
When you open a recovery file at first, files are verified automatically and the result is saved.
|
|
When you push "Repair" buttom afterwards,
|
|
the result is re-used and most part of actual verification will be skipped,
|
|
then the speed becomes faster.
|
|
By default setting (<b>For a time</b>), GUI keeps the result until it is closed.
|
|
When you set a longer period (<b>For some days</b>), GUI keeps the result for the period.
|
|
<b>Caution !</b> with this setting you may see the <b>past status</b> of files.
|
|
If you want to see the <b>current status</b> of files, push "<b>F5-key</b>",
|
|
then all files will be re-verified newly.
|
|
The data files are "<tt>***.bin</tt>" or "<tt>***.ini</tt>" in "<tt>save</tt>" folder.
|
|
Though old results beyond the period are erased,
|
|
sometimes those files may become many and large,
|
|
then be careful about setting long period.

<dl><dt><b>

Don't search subfolders
|
|
</b></dt><dd> 
|
|
When a file is missing, it will search the misnamed or moved file in folders recursively by default.
|

If you want to ignore subfolders by the reason of taking time, check this option.

<h3>PAR2 options</h3>
|
|
|
|
<dl><dt><b>
|
|
Save UTF-16 filename additionally
|
|
</b></dt><dd> 
|
|
MultiPar supports "Unicode Filename packet" (UTF-16 filename) in PAR 2.0 specifications.
|
|
Only when you use non-ASCII characters in filename,
|
|
and you send PAR2 files to someone who has another PAR2 client which supports the packet,
|
|
you should check this option.
|
|
Usually it is worthless, because most PAR2 clients ignore the packet.
|
|
No need to check this for MultiPar and par2_tbb, which use UTF-8 filename.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Use file index for volume number
|
|
</b></dt><dd> 
|
|
Standard PAR2 filenames contain how many recovery blocks as their volume number.
|
|
If you want to use index of files instead of number of blocks, check this option.
|
|
When you transport PAR2 files over UseNet, you must not check this,
|
|
because the number of blocks is important for downloaders.
|
|
</dd></dl>
|
|
|
|
<a name="packet_repetition"></a>
|
|
<dl><dt><b>
|
|
Packet repetition
|
|
</b></dt><dd> 
|
|
When you create many recovery blocks, the PAR2 files may have many repeating packets.
|
|
You can disable or decrease the repetition of packets.
|
|
If you want smaller PAR2 files,
|
|
you may select "<b>Not used</b>" (no repetition) or "<b>Upto # times</b>" (packets will be repeated upto # times.).
|
|
If you create only one recovery file, you should select "<b>No restriction</b>".

<h3>PAR3 options</h3>
|
|
|
|
<p> 
|
|
My sample PAR3 is implemented only for personal testing purpose.
|
|
Because I modify its algorithm and format sometimes while writing the proposal,
|
|
current samples won't be compatible with future PAR 3.0 specifications.
|
|
This section would be obsolete in future versions.
|
|
</p>
|
|
|
|
<dl><dt><b>
|
|
Create PAR 2.0 compatible PAR3 file
|
|
</b></dt><dd> 
|
|
If you want to create PAR3 files which enables verification by PAR2 client, check this option.
|
|
PAR2 client like QuickPar can use those PAR3 files for verification.
|
|
Because PAR3 recovery data is not compatible for PAR2,
|
|
PAR2 client cannot recover lost files with PAR3 files.
|
|
</dd></dl>
|
|
|
|
<dl><dt><b>
|
|
Use incomplete recovery
|
|
</b></dt><dd> 
|
|
Only when you cannot repair files by the lack of recovery blocks,
|
|
you may try this option.
|
|
This method retrieves damaged blocks from corrupt files,
|
|
and tries to repair them as possible as it can.
|
|
For setting, low value will read more damaged blocks and slow,
|
|
and high value will read less damaged blocks and fast.
|
|
When "Delete damaged files after Reapir" option isn't checked,
|
|
if the repair is failed, "<tt>.incomplete</tt>" is inserted into filename and lost area is filled by zero.
