File : Repair collection

File : Repair collection makes it possible to recover from integrity problems in your collection (e.g. as a result of physical damage to the collection files). You can quickly run Repair collection by choosing Ctrl+F12 or clicking the red-cross icon on toolbar

Note that recovery is only possible in full access mode. To turn full access on choose Tools : Options or press Ctrl+O and select Full access at Data access : Access mode

Integrity problems in a collection may appear in case of hardware or system software problems. Bad clusters, lost sectors, data corruption, etc. can often be remedied by replacing affected files (e.g. corrupted Mpeg file, etc.). However, if the problem occurs in SuperMemo index files or files storing optimization data used by repetition spacing algorithm, only File : Repair collection can remedy the problem.

Important! Never run Repair before making a back-up copy of your collection files (e.g. with File : Tools : Quick backup)!

Before you begin recovery, choose appropriate recovery options in Recovery Options dialog box.

Repair collection does not recover from some error types. Here are some errors that are not remedied with Repair collection:

Note: If you encounter problems that could not be remedied with File : Repair collection (except for those listed above), please report it to SuperMemoMail (please make a back-up of copy of the damaged collection, e.g. with File : Tools : Quick backup).
