I only have one profile in Thunderbird. It has grown to 52 GB. I often transfer my profile between a light weight laptop and my desktop. I am trying to delete files to reduce the overall size of my profile down.

I found a file with a .pcv ending, dated 2018 (we are now in 2025) - can I delete it.

Also is there a spot where the various file formats are discussed ie MSF file, NSTMP files, .pcv, .sqlite, .sqlite-wal, sqlite-snm, metadata-v2

"A pcv file is the backup format of MozBackup."

I know nothing about MozBackup. I assume that you can delete a back-up file without affecting Thunderbird.
