sync.ffs_lock
in folders that are part of the folder-pairs setup by user - but these files could be easily made less intrusive
For comparison Microsoft Office 2010 Excel creates locked files whenever it opens a spreadsheet file - but it does it gracefully by creating e.g.
~$test file.xlsm
doppelganger for a file named
test file.xlsm
So Excel makes them highly noticeable and expected always in the same place - i.e. at the beginning of the list of files in a folder. And yes: I know that the order of the alphabet sort does not change- and thus the sync.ffs_lock will always be in a predictable place. But this is still impractical for file handling, because are users expected to always remember what folder is monitored and to also check if it is occurring in a given moment - or suffer the annoying consequences of coping / moving / mass-renaming / deleting of items that were blindly selected en masse (like with the CTRL + A shortcut) i.e. selected with inclusion of that blocked FFS_LOCK file? And again yes: I know that this file is hidden, so it theory should not interfere with handling of others - but in practice some of those others files can also be hidden and thus I personally often have visibility of hidden items turned on in my daily used filemanager
And so, I propose appending / changing name of the FFS_LOCK file, so that it too would always be at the top of files sorted with alphabetically descending order. Or even better: to give users the ability to choose the name for this file, so that they themselves can make them be placed precisely (before or after such Excel temporary files) and / or to make them stand out / be easily findable by changing their names to for example
SSSsync!!!.ffs_lock
or
ZZZ██████████ temp.ffs_lock
I myself would use some ZZZ-beginning-long-name, because whenever I would have doubts if a given folder is monitored / locked, then 99.99% of time I could just push down the Mouse Scroll Wheel and scroll it down with just one swift finger movement - because such action would practically instantly reveal the end of list of files and thus quickly inform me visually if the FFS_LOCK file for current folder is present
