Problem with command line

[admin]

Turns out they are REGISTRY change files and BCD Edit change files.  Problem is LIVE Windows won't let you mount the EFI partition so it can be edited... at least not for the general Admin user.  I then loaded my favorite WinPE with the tools I need... even then it wouldn't let me mount the EFI partition with a drive letter.  I then used a partition tool to change the basic ID of the EFI partition to a basic DATA partition, after that I was able to mount that partition with a letter for editing.  I went into the partition and carefully removed all those old (2023) files (mentioned above), dismounted the partition, reset its ID back to EFI then exited.  ReBOOTed the System and all is OK and most of that extra storage in the now 200mB EFI partition was gone.

On older Legacy-MBR Systems, that stuff is either in the MSR partition (if you have one) or located in the OS partition.  Both of those are usually larger than the 100mB DEFAULT EFI partition generated on UEFI-GPT Systems.  I'm not sure what happens if you need more space than what is available when an edit is being done by the System during an EFI update... I don't really wanna find out  .  I do mess with my BCD and REGISTRY quite often... I guess I need to be concerned in this area.

Hasleo Devs... any great and glorious knowlege to offer us in this area? 

We tested with a simple BCD and determined that the files were generated by an ID stored in the BCD file, and that loading and unloading the BCD file multiple times would not result in more files, even if the BCD file was copied to a different location. 


Yet on one of my computers that I've had for years, there are no .TM.blf and .regtrans-ms files generated based on multiple IDs.


Did you regenerate the BCD file for that partition? Or has some other program changed the ID stored in this BCD?
