Great stuff, I tried the last one you recommended Universal editor, opened up a 11GB file easy. Nicos said on March 25, at am. But i am only going by what i have seen first hand so there may be some technical issues behind that scenes that are beyond my knowledge that contradict what i think. But i have to go by what i have witnessed. It would be interesting to hear from someone with more knowledge about memory usage where database is concerned.

If you were to do as Renee suggested you could setup your record id's to be the line numbers. Then you could use a select statement and select whatever line you wanted. This could all be done dynamically if you set it up the right way.
And i tested sql compact with , records and it was very quick. Seconds is all it would take to read through your lines. I can't remember for sure but i believe i was able to do as much as 15, records per second on an insert. I also want to say that i filled a datatable with , lines in about 3 seconds. Don't quote me though, it's been about 2 months since i played with it.

John, Maybe you could post the code for omer? Omer, it would probably help if you could post some code of yours also so everyone can see why it is an issue on your end. Not much in the way of code, but here it is: Code Snippet. Thursday, May 1, PM. Monday, May 5, AM. Thank you four yourcode. I have downloaded it recently.

Jgalley, I read your project with great interest. I thought it was a really good project. It's true I have turned to databases rather than serialized solutions.
JW: " I doubt that using a database would result in better performance. Omer, I didn't post anything else about the database idea for you because i wasn't sure you wanted to go that route after the other posts.
But if you are still interested in the idea here is the basic idea to get it done: first you need to create your database with 2 tables.
