FreeFileSync Forum

Thanks for your replies. I've just purchased the Donation Edition of FreeFileSync and updated to the current version 12.1. I now find that "GlobalSettings.xml" has "C:\" instead of "FFS:\" for references to config files (and log files). :-)

Recently, I've been looking in the GlobalSettings.xml file and notice that references to config files (and log files) start with "FFS:\" instead of "C:\".

For example:

FFS:\FFS Configs\My Test Config.ffs_gui

instead of

C:\FFS Configs\My Test Config.ffs_gui

Could you please advise why does the ...

Yes FFS checks disk space and shows a warning when starting sync.Zenju

Great - thanks for confirming.

After running a Compare, does FreeFileSync provide a warning if there may be insufficient disk space before attempting a Synchronise? If not, could this functionality be added to a future update?

As FreeFileSync is open source, would it be possible to run it and step through the code with a debugger to find precisely where it is failing?

I really like FreeFileSync Portable. Version 6.2 still seems to work well, but it would be really nice to be able to use a newer version, as 6.2 is about a ...

Hi,
I know that questions about undoing a sync have been posed before, but I don't think they addressed this particular aspect...

I am trying to merge and streamline my photos and I just mistakenly sync'd two folders. One (Folder 'A') had 1500 photos, the other (Folder 'B') had the same 1500 ...

Thanks for your reply Zenju.

Please could this be confirmed? Many Thanks.

If a filter is added to an existing profile (and Mirror is being used), what happens to files/folders on the right-hand side that have been filtered? Are they just ignored and left as is, or deleted to make it match the left-hand side?

For example, if a filter is added to exclude the folder "Test ...

It's possible to exlude files by size via filter. FreeFileSync respects this setting during a binary comparison.Zenju

Thanks for your reply. However, this existing functionality would skip a "large" file completely rather than comparing just the first part of the file's contents.

Would it be possible to add a Quick Contents Compare option that only compares the beginning of a file, with a user-specified Quick Compare Limit? WinMerge 2.14.0.0 has this feature. This could flag different files that a date/time and size comparison would miss (and a full comparison takes too long ...

In addition to checking the date/time and size of a file, would it be possible to also consider the checksum of a file (e.g. MD5 hash)? This would flag if a file's contents has changed, without looking at the entire file (usually too slow).

BTW, is it possible to obtain a file checksum (say from ...

Would it be possible to add the functionality to show the date/time when each configuration was last synced?

The log file behaves like a ring buffer.Zenju

Thanks Zenju - that was just what I was hoping for. :-)

Just curious - what happens when the log file becomes larger than the value specified by LastSyncsLogSizeMax?

1) Is the old log file deleted (either permanently or moved to Recycle Bin), and a new blank log file is created from scratch?

or

2) Is the existing log file kept with newer entries added ...

Thanks for clarifying Zenju.

Thanks for clarifying Zenju.

Thanks for the clarification Zenju.

I really like the ability to detect moved files and deal with them efficiently.

I plan on doing something similar, but will create two configurations for each of the backups that I run independently. I prefer not doing the backups at the same time if possible, so I would have another untouched working recent copy should anything go wrong.

From the help - "FileTimeTolerance. By default file modification times are allowed to have a 2 second difference while still being considered equal. This is required by FAT/FAT32 file systems which store file times with a 2 second precision only."

Therefore, does the FileTimeTolerance setting ...

Could this be when FFS enumerates all the available drives? i.e. When there is a Variable Name specified and it checks across all available drives to see which drive actually has this volume name?

Thanks for your reply Zenju.

So file movements are not detected when a FAT32 system is in use. I am using a Mirror sync from my local hard drive (NTFS) to my flash drive (FAT32). This would explain why synced files are deleted and recopied again on the destination (instead of just moving on the ...

According to the FFS tool-tip, the "Detect Moved Files" feature is "Not supported by all file systems". Could you please advise which file systems are/are not supported? If I do a Mirror sync from a NTFS local hard drive to a FAT32 flash drive, will I be able to fully utilise this feature?

I notice that only when using Variable Drive Letters, it causes some brief activity on the internal floppy disk (signified by the floppy drive sound and the floppy disk LED lighting up temporarily) - even though none of the Variable Drive Letters I am using are related to the floppy drive!

I really ...

Is there an easy way to tell the date/time when a configuration was last synced (without having to look in log files)? For example, it would be nice to know at a glance when I last did a backup (sync) to my USB flash drive to know how current it is. I'm using FreeFileSync 6.2 on XP (portable version ...

When copying a file manually in Windows, the created date/time stamp is set to the current date/time. However, when FFS copies a file, the created date/time stamp is set to the original. Just wondered why there is this discrepancy in behaviour?
