When you push "Preview" button on <a href="create.htm">Create window</a>, this window appears.

|
|
Because the size of recovery files are hard to predict for most users,
|
|
MultiPar has "Preview" feature.
|
|
You can see the list of recovery files which you will create by the current setting.
|
|
You may consider the efficiency of those files.
|
|
If you are satisfied with them, you may create recovery files directly by pushing "<b>Create</b>" button.
|
|
Or you may return to Create window by pushing "<b>Cancel</b>" button.

Source block usage

|
|
This rate is a measure of block allocation.
|
|
When a file size is different from a multiple of block size,
|
|
the reminder in the last block of the file becomes a waste.
|
|
If all source blocks are filled by file data fully, the rate becomes 100%.
|
|
When it is lower than 90%, you may decrese the block size.

Recovery block consumption

|
|
This rate is a measure of recovery file's construction.
|
|
While recovery files consist of many packets,
|
|
there are some packets which don't contain recovery data.
|
|
If packets for recovery blocks consume most of the recovery files, the rate becomes high.
|
|
When it is too low, you may decrease the number of source blocks,
|
|
or limit <a href="option3.htm#packet_repetition">repetition of packets</a>.

Efficiency of recovery files
|
|
</b></dt><dd> 
|
|
This rate is a measure of recovering capability.
|
|
For example, when the rate is 95% for recovery files of 300MB,
|
|
you will be able to recover upto 285MB.
|
|
Because this value is just an avarage assumption,
|
|
actual possibility depends on the distribution of damage.
|
|
The efficiency is important, when you save recovery files in a limited size.
