FreeFileSync handles these virtual drives flawlessly, giving you the security of a vault without Microsoft's proprietary API restrictions.

Thank you, that seem to work.

Here's something that may help.

If checked, then ...

Thanks for replying, though I have checked both but none satisfies my needs.

For VeraCrypt, the problem is it's a single file. Syncing a 10GB file is quite fast on a local drive, but may take hours to a cloud storage. I can break it down over several containers, but that would be tedious to update ...

Hey, sorry for the late reply.

I did end up solving the issue by running FFS as administrator. I'm not sure why this is necessary though, when the permissions are set correctly.

Prior to making this post, I was actually running a version of FFS at least 1.5 years old and I still had this issue. I ...

To prevent confusions:
It is not RealTimeSync (RTS) you are talking about, it is FreeFileSync (FFS). Plerry, 21 Mar 2023, 10:42

You're right man, thanks. I was in a rush when I read the instructions, I'll try it later.

To prevent confusions:
It is not RealTimeSync (RTS) you are talking about, it is FreeFileSync (FFS).

In order to run FFS minimized, you need to save your sync configuration as a *.ffs_batch file, and follow the instructions as described here.

Ok. I found what the problem is but please help me solve it.
RealTimeSync shows a pop-up windows once it opens.
After synchronization, pop-up stay on. If I minimize the pop-up, it starts synchronizing.
I need to make this pop-up minimized.
I'm running Win11 64bit and FFS donation 12.1. Thanks.

Hello people, I'm running the latest FreeFileSync "donation edition".

Hello.

I have created an NTFS VeraCrypt partition on an external drive, then renamed it as "EXT_DRIVE" partition name.

Hey,

Scheme I do is:
Encrypt with Peazip straight to a Veracrypt partition.
Already from Veracrypt I send to Google with P Frrefilesync.

PS. I have backup versions of the system, so I got the older global settings file and replaces. Well, so far, no message.

Thank you for the detailed explanation, John!

Thank you, JDB! I didn't know about VeraCrypt - I'll test it out! EDIT: It's a still-alive project, updated recently! Yay!

Hello,

Adding my experience here --

I have created encrypted volumes using VeraCrypt -- https://www.veracrypt.fr/en/Home.html

It works very well. VeraCrypt is a spinoff from the TrueCrypt project that was relenquished by its original developers.

One nice aspect of VeraCrypt is that it runs on ...

I apologize for not understanding the question fully and expanding this into a broader topic. I don't usually try to be a pompous buffoon, but sometimes it turns out that way! Sorry, netnet.

I'll add my results with VeraCrypt to the other post that Plerry referenced.

If you are going to try using Veracrypt then it is worth mentioning the following.

I will refer to the file that Veracrypt creates (to hold your data inside it) as the Veracrypt file . I will refer to the mounting of that file as a drive letter as the Veracrypt volume -- you would actually copy ...

I don't remember what is the option's checked state (I don't have VC on this machine to check), but it should be set to change the container time according to last write/access time.

FFS checks if the file has been modified by it's modification time (in the file's metadata) and size*. VC containers ...

... the whole point of FFS is to sync your files when changes are made. What am I missing here? Do you have this unchecked because of the size of the Veracrypt volume as a several GB volume will each up a lot of resources and network time, if your sync location is in the cloud. What does FFS use to know ...

Also make sure VeraCrypt's option to not update container file modification time is unchecked. It will prevent FFS from detecting that the files has been changed, and it will not sync. I had this problem.

FFS only supports folder selection, so Veracrypt files can't be synced unless they are mounted and given a path

I think I figured out a workaround. I named my Veracrypt container file as Private.hc, but could not copy this file to the Compare window in FFsync. It would only copy the Parent Directory, which in my case was D:. I then when into the Filter section and deleted the * from the Include list and added ...

... I try to browse to the File on my D: drive I cannot find it because FFsync appears to only show folders. The container file I have created with Veracrypt is in my Root directory of my USB drive and is not within a folder.

Is this a feature or bug that I cannot select this file for Syncing purposes ...
