Cannot open saved ppk2 session data files "1.60920136 gigabytes, but the application you are using is limited to 1.073741823 gigabytes"

[JvT]

During some test I saved a couple of session data files in the PPK2 tool v3.5.3

After trying opening it, I get the following error: 

08:59:31.165 The file: C:\ppk-20230116T132437-data-logger.ppk requires 1.60920136 gigabytes, but the application you are using is limited to 1.073741823 gigabytes

08:59:31.167 Error loading from C:\ppk-20230116T132437-data-logger.ppk

The file is 493.911 KB and not 1.60920136 gigabytes.

I already tried to make the sampling buffer size in the advance menu bigger, as that is the only option I could find about data size limits but I cannot make that bigger then 1073 MB.

Has anybody a solution for opening these files?

Hello,

I have the same issue with opening files. I've also tried open them on Linux and iOS.
I get the following error message: "The file: F:\ppk-20230616.ppk requires 2.99880136 gigabytes, but the application you are using is limited to 2.147483647 gigabytes."
The PPK-file size is only 4 megabytes.
Power profiler version v3.5.5

Best regards,

This is because .ppk files are compressed, so when opened they are much larger than the file size indicates. You need to reduce the amount of allocated memory, to something that gives an estimated RAM requirement lower than 1GB. The "estimated RAM requirement" can be seen above the start button in the Power profiler app. We've not yet released a fix for this on Windows I'm afraid. The only way to open this file would be to use the MacOS or Linux version of the Power Profiler app.

Best regards,

Simon

Thank you for quick reply.
I have tried to open on MacOS and Linux already. I wasn't able to open it on either of those.
I've tried to copy the files also, with no luck.

What kind of error(s) are you seeing on the other operating systems? I can ask the devs if there's anything we can do here if you really need to review this specific file, but if possible I'd recommend decreasing the RAM requirement as explained and do a "smaller" sample measurement that is readable. 

Best regards,

Hi,
there are same errors on all operating systems ("The file: F:\ppk-20230616.ppk requires 2.99880136 gigabytes, but the application you are using is limited to 2.147483647 gigabytes.").
Is there any way to increase RAM-memory for the Power Profiler -program? In advanced settings I can reach only 2147MB.
And yes, it would be great if there is any way to open files. I have multiple files with same issue, those measurements were time consuming.

Best regards,
IK

I've forwarded this as a request to the devs. I can't guarantee anything, but I'll let you know when I hear back from them. Either way, for future reference I'd recommend not to max out the power profiler measurements in the Power Profiler app.

Best regards,

Simon
