Thundrbird odd files in cache2 & cache2\entries directories/folders

OS = Windows 7 (64 bit) Browser = Firefox version 84.0.2 (32-bit) Thunderbird = Thunderbird version 68.8.1 (32-bit) Synchronization software = Microsoft SyncToy version 2.1 (64 bit) External hard drives = Samsung 5 TByte

My normal procedure for keeping my three (3) computers synchronized is to run SyncToy at least once a week. That puts the latest version of any piece of data on all three computers. I then synchronize my main computer to three (3) 5 TByte external hard drives.

SyncToy is known to screw up when it cannot determine which data file is the newest by the file date in it's cache file (a Microsoft .dat file.) I end up with test.txt and test.1.txt on some hard drives as a result.

This past week I discovered my Thunderbird directory/folder increased in size tremendously. Numerous files in the directories/folders cache2 & cache2\entries have two (2) files with the same name except for one (1) of each file has a .1 on the end. The size of the files seem to be identical.

Example: 0710D3592D67032272A741CF6F0F4734A5F29E16 0710D3592D67032272A741CF6F0F4734A5F29E16.1

Before I delete the files with the .1 extension (hundreds and hundreds of files) I am asking if this is a SyncToy screw up or is something wrong with Thunderbird.

Any help would be appreciated.

The .1 extensions were indeed caused by a SyncToy screw up. Deleting the files caused no problems with Thunderbird.

As an aside, deleting 7,000 plus cache files that were older than dirt caused NO problems with Thunderbird. Sure would be nice if a way to automatically remove old cache files was available within Thunderbird.

lets start with if it is located in the local low or local appdata folders it is not required. especially the cache files.

Thank you for your reply.

I should have mentioned that all my computers have their hard drives partitioned into three (3) drives. C: is for the operating system, D: is for the software installed by me, and G is for data.

Almost all of Thunderbird was installed on G: as if the installation was on a thumb drive. There are some files in the C:\Users\XXXXXX\AppData\Local\Thunderbird folders that point to the installation on G: .

The additional dot one (.1) files I am concerned about are on drive G: .

Thanks again.
