In infinite analysis, when Rybka analyzes my position of chess for a few minutes, a persistent hash file is not automatically created at the specified path. Also, Rybka doesn't create a saved hash file when I press the "Save Hash" button in the Rybka engine parameters windows. What is the problem? When I search my whole hard disk for 2 files with the extensions of *.rph and *.rsh, none is found there.

I fill in 2 paths without quotes in the 2 edit boxes in the Rybka engine parameters windows as follows below:

1. Persistent Hash File = C:\hashfiles\persistent\

2. Saved Hash File = C:\hashfiles\saved\

In addition, I check the "Persistent Hash Enabled" box. Besides, I would check the "Preserve Analysis" box if I plan to use an *interactive* infinite analysis.

I successfully made a clean install of Windows XP on my computer last month and I updated everything. The Windows XP SP3 looks very healthy and almost everything is at default.

My Rybka uses 256 MB hashtable.

Please help me to solve the problem so that Rybka will successfully create 2 hash files automatically.

I am waiting for your help.

Thanks in advance,
Eran Karu

Wrong! What part of It should point directly to the file itself (ie. not just the directory) is so hard to understand?

Persistent Hash File = C:\hashfiles\persistent\Foo.rph

You can also use relative paths, e.g. just Foo.rph.

Okay, how can I point directly to the hashfiles themselves when filling in the "Persistent Hash File" edit box and in the "Saved Hash File" edit box if the hashfiles do not exist? I am puzzled and I do not find any answer or information in the Rybka manual or in the FAQ. Please explain to me very clearly.

Thanks again,

They will exist after Rybka creates them. See the examples in my previous post.

Now it is clear to me. :-)

When I fill in the edit box a name of the path *with* a name of a new file as follows below:

C:\hashfiles\persistent\Foo.rph

Then when Rybka loads, it creates the new "Foo.rph" file on the hard disk.

Thank you for your help. :-)
