Split SDLTM/TMX files

Hello,

We have a huge SDLTM with 280081 TUs and we want to create a GS TM from it.

We have succeeded in creating the GS TM, but have not been able to import all TUs. At first, it was due to a "server connection" error (probably connection was lost for one reason or another). We have tried several times since then, but we always get this "server connection" error or just an undefined error.

Our GS TM already has 198191 entries, which is a more than generous amount of entries, but ideally we would like to add them all, so we thought about splitting the SDLTM (or an exported TMX, we don't mind) into several TMX to streamline the process.

The only viable option we found so far is Heartsome TMX Editor (https://github.com/heartsome/tmxeditor8), but when we download the ZIP, unzip it and try to run the "executable" file (there are two .exe files within that ZIP), we get an error message stating that the version of this file is not compatible with our Windows version (W7, 64 bit) and cannot do anything.

We tried downloading the "Microsoft Windows XP/Vista/7/8" recommended installer (from abovementioned URL), but the OneDrive link is no longer working...

Could anyone help with this issue?

Thank you in advance.

Best regards,
