Hi, this is my suggestion for future builds
1) a new sync mode "clean and update" (only 1 pass instead actual 2 pass first clean and then update), and/or clean addable at other sync modes
2) add more comparison mode:
a) only time/date, and add extended optional mode for overwrite target files even when source file is oldest
b) byte size only
every time the byte size is different in all case source file will be copy and overwrite the target file (with the update and mirror update sync mode).
c) byte size time/date
first pass copy from source and overwrite all file in target with different file size (even if have exactly the same time/date, or if source time/date is oldest), second pass copy from source and overwrite target files when file size is exactly the same but time/date is different
with this comparison mode target will be in every case an exact copy of source when used with sync mode mirror update/update
3) (multiple) task time scheduling for programmable auto sync
4) auto-sync option when source is modified (update with a selectable retard of xx seconds/minutes/hours), and option for auto-sync in real time every time source was modified
5) option for delete file/folders in recycle bin, and for erase file/folders in n. random pass
In version 2.1.1 in some case with Update mode, file sync is made from target to source, maybe this is a bug (?!)
Sorry for bad english
