Required Software and APIs

APIs used when syncing to remote targets (only works between Linux machines):

Parsing filetree (Listing files): Run via a temporary uploaded python script on the remote side*
Moving (renaming) file: Run via a temporary uploaded python script on the remote side*
Copying file: uses rsync with the "--files-from" option. (also using "-e ssh" option) (see source code for the exact command)
Remove file: Run via a temporary uploaded python script on the remote side*
Remove folder: Run via a temporary uploaded python script on the remote side*
Create folder: Run via a temporary uploaded python script on the remote side*
realpath (converting fiPath to fsPath): ssh ... realpath (So it should be subject to the special-character issue (but it is only used for database-file, filter-file etc))

*A python script is uploaded to the host (to the /tmp folder) (when clicking T2T>Compare or T2T>Sync).

Moving (renaming) file: Windows: fs.promises.rename; Other: fs.promises.rename

Copy file:: Windows: copy /l (one entry per call); Other: cp (one entry per call)

Remove file: Windows: del (one entry per call); Other: rm (multiple entries in one call)

Remove folder: Windows: rmdir (one entry per call); Other: rmdir (multiple entries in one call)

Create folder: Windows: mkdir -p (multiple entries in one call); Other: mkdir (multiple entries in one call)

realpath (converting fiPath to fsPath): Windows: fs.realpath.native; Other: realpath

Open (txt-) files or folders in default program: Windows: start; Other: xdg-open

Getting metadata from a single file (not used when parsing tree)

Windows: fs.promises.lstat(fsFile) (only 3 decimal timestamp)

Other: fs.promises.lstat(fsFile) (only 3 decimal timestamp)

or using stat (Bash) (9 decimal timestamp)
