*.7z files are 1st synced and then deleted over and over

[ghrasc]

a source folder containing one or more *.7z is synced to the target folder, immediately thereafter the *.7z is/are deleted from the target folder.
Log file looks like

09/22/21 08:33:54 : INFO:    Starting CryptSync
09/22/21 08:33:56 : INFO:    syncing folder orig "C:\Temp\Source" with crypt "C:\Temp\Target"

09/22/21 08:33:56 : INFO:    finished syncing folder orig "C:\Temp\Source" with crypt "C:\Temp\Target"

over and over.

Renaming the files to any other file extension (e.g. SampleFile1.myzip) solves the issue.
I guess until this is solved one should use SyncPair7zExt0 == 0 (uncheck the box "Use .7z instead of .cryptsync ...")

System:
Win7x64 SP1 ENU

P.S. How to reproduce?

• take a clean machine with Cryptsync
• create 2 empty folders: "Source" and "Target"
• (optional: copy several files into "Source")
• add 1 or more *.7z to source
• configure CryptSync to encrypt and compress "Source" to "Target", "sync unencrypted to encrypted only"
• enable/run the configured sync
• inspect the log file, search for "does not exist in src folder, delete file"

but you also got *.7z in the list of files to copy only and not compress/encrypt?

[ghrasc]

Yes, I 1st got "*.*" in "files you don't want encrypted but copied", now only "*".
Please find a sample config at https://ufile.io/8vxqd1uf (only 2kB, so "slow download" is good - in case you want to directly import pls see #35 (comment) for the HowTo).

Another 'funny' workaround I found today: When enabling SyncPairEncnames0 the bug does not appear to happen. Maybe that helps finding the issue.

P.S. Some runs ("Interval for full scans" is over) it only copies the files, in the next run it only deletes.
Some other runs show the log from 1st post where copying and deletion happen immediately after another.
