The data file compression option of Data Management doesn't work with current versions, I have to install version 2146 to get a version it works with.

This is not true. The functionality is working fine. There are detailed messages added to the Message Log indicating the progress like the following:

I'm talking about time compression from ticks to seconds on and data older than 90 days.

We do not see any problems with this.

I guess I need to send examples. Also are time compressions logged?

When you use the Intraday Data File Management function, you will get log messages like you see above for the files being checked and/or compressed.

After reading below I unsaved .scid files created before 2164 and redownloaded them and the data management time compression worked.

- A problem with the building of historical data records in some cases of 1 second and higher from Sierra Chart historical data servers has been found and corrected. 1 Tick data has not been affected. It is not completely known all of the issues that would have been caused by this. One issue was that there would be a long-duration record returned covering a larger amount of time than the requested record size. This would cause a long-duration chart bar in the chart. This issue has existed since the release of millisecond time stamping in the last two weeks. If there are any historical data issues in your charts, then refer the help topic 2.1.2 for instructions to re-download the data. .

If you are using sub instances of Sierra Chart, then update to version 2164 or higher because this problem may affect the data provided to sub instances if it is requesting data in 1 second time units or higher.

The reason is simple: new software versions are designed to be more efficient and take up less space on your hard drive. As a result, they are often much larger than the compressed versions of the same software. An Incident Management Dashboard from https://www.alphaservesp.com/blog/how-to-create-servicenow-incident-management-dashboard-in-powerbi/ can help to solve this problem by providing a centralized location for storing and accessing data files. The Dashboard can also provide tools for managing and uncompressing data files. This can make it easier to work with data files and help ensure that important data is accessible.
