    1. CONice solution. In fact, this is the best one given the description I gave of my problem. We can also enhance it: at file generation append new names at the end of the file instead of the top (avoid opening and reading the whole file), and at file access just read the first line and remove it from the text file (I'm sure there are ways to do that without having to read the whole file too). I mark this solution as the accepted answer, although the solution [given by Lucasmus is also pretty clever](http://stackoverflow.com/a/13378514/1121352).

    2. COIn my final solution, I will implement another variant of the indexing concept: I won't generate the names randomly but using a deterministic pattern with an increasing numbering (eg: file1.ext, file2.ext, file3.ext, etc.). Then I will keep an index file that will store 2 fields: the current ID (eg: 1 for file1.ext), and the last ID of the latest generated file (eg: 1999 for file1999.ext). This has several advantages: the index file is always very short; I can always access directly a new file; and lastly I can also count the number of files left without listing the files

    3. COby computing latestID - currentID, which allows me to run a background thread that generates new files as we run under a specified threshold. In the end, we get an almost constant access time for these two operations: accessing a file and counting the number of files left. Con is that I must be careful about concurrent accesses to the index file and the generated files to avoid unsynchronization (as a failguard, I can just regenerate it when I encounter an exception with a try: except: block).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
