The file manager is used to for maintain and fix problems with the data files. You should rarely, if ever, need to do anything on this screen.



Tag All

Untag All

The file utilities operate on selected or “Tagged” files, ones with the checkbox checked. These two buttons let you tag or untag all files on the list before running one of the utilities.


Build Keys

A file key is like a book index. It lets the program know where in a data file a particular record is located. When a key becomes corrupted, an uncommon occurrence, the program may think that a record is missing though it really is there. A given file can have multiple keys to make data access more efficient. Press this button to rebuild all keys for the tagged files.



When a record is deleted from a file, the information is not really deleted. Rather, it is marked as available space in the file for the next record that is added. If you do more deletions than additions, the file becomes full of “holes” for the deleted records. While there is no problem having these deleted records, it does make the files bigger and just a little slower. The Pack button compresses the data and rebuilds the keys. Since a file is more likely to be added to than removed from, Pack is usually the same as the Build Keys button above.



Some program operations require that a data file is temporarily locked to prevent other users from changing it while the operation is in progress. If the computer freezes or crashes while a file is locked, the program cannot unlock it normally and you may not be able to use the program effectively. This button unlocks errant file locks on all tagged files.



When a data file is hopelessly corrupted and you do not have a recent backup, this fix function can sometimes recover your data. It is not a guarantee and only works on certain kinds of data corruption.


Before you can use the fix function, you must make a current backup of your data and a the program will not let you proceed without one.


WARNING!   The Fix function is a last resort when all other attempts to recover the data in a damaged file have failed. If run on an undamaged file, it can actually cause damage. Because of the potential to cause more harm than good, this function is locked and can be accessed only with a code provided by technical support.



Freshen makes a copy of the data file, clears the original, adds the records back to the original file, then deletes the copy. This process removes undesirable duplicate records, corrects minor data corruption, and rebuilds the keys. It is much less rigorous than the Fix function and is not locked. Nevertheless, it is a good idea to make a backup of your data before running this function.



If a data file Disk Name shows “Error 2: File Not Found” instead of a file name, it means that the program has not yet needed to store information in that file and so has not created it. It is not an “error” that need concern you. However, if you don't like seeing it, you can create the file yourself. The Create button creates any missing files that are tagged. It does not recreate, and thus wipe out the data in, files that already exist.



This tells the program to read the data file and list the information about the file. The above screen was obtained by first choosing the Tag All button followed by the Information button.


HINT:   Whenever you upgrade Aeris, choose the Tag All button followed by the Information button. This not only lists the file information, it converts the data in any files whose structure has changed in the newer version.
