Cannot save Sessions to file, > 65535 entries.

[Robert]

I am trying to save sessions to a file, there are around 58k of them

I am getting the error saying the number of entries is 65535 or greater.

The error says you can set 'UseZip64WhenSaving' property on the ZipFile instance... can you please do this or expose the option to us?  (Or do it automatically when needed...)

 

I see you said it was fixed in FiddlerCap in 2014, so I'm curious why it's still broken in Fiddler Classic... [see below link]

Maybe because it already does enable it 'when needed' but it doesn't think it's needed because i only have < 60k sessions, but somehow it's expanded to > 65535 when it tries to save?

Hello Robert,

 

Thank you for reporting this issue!

We can confirm that this is a limitation that leads to an error when you try to save a SAZ with too many sessions. Because each session in a SAZ file consists of several files (more details of the SAZ file format here...), the maximum file limitation for the archiving library is hit before reaching 65k sessions (it will happen with more than 20k/30k+ sessions).

While the team is researching a possible solution for Fiddler Classic (Fiddler Everywhere already uses a different archive library that does not hit the limitation), you could temporarily work around this by creating smaller SAZ files and selecting smaller session portions. For example, select 5k sessions, make a SAZ file, and then do the same with the other sessions.
