If you don’t want Sync to track some files in your sync folder, please use IgnoreList. IgnoreList is located in the hidden ".sync" folder inside your sync share.
IgnoreList is a UTF-8 encoded .txt file that allows you to specify single files, paths or rules for ignoring during the synchronization job. Each line of the IgnoreList file represents a separate rule. All the files that fall under the ignore filter are not indexed and not counted in the “Size” column in Sync main view.
Please note: IgnoreList is case sensitive!
IgnoreList supports ‘?’ and ‘*‘ wildcard symbols.
‘?’ substitutes any single character in a filename
‘*’ substitutes a string of several (any number) characters in a filename
For example, an IgnoreList containing the following entries:
will force to ignore all the .PDF files in your sync folder, as well as all .TXT files starting with ‘abc’, followed by some letter.
Each line in the ignore list can represent both a directory and a file. For example, this line:
will force Sync to ignore all the files called “My Test”, as well as all the directories called “My Test”, including their content and all subdirectories.
If an ignore filter consists of 2 components, it will be applied to the root of a sync folder. For example:
will ignore subfolder “CDE F" of “ABC" which is located only in the root of a sync folder. The folder "123\ABC\CDE F" will not be ignored.
will ignore all files in the folder named “FOO” located in the root of a sync folder. If you want to ignore all the “FOO” folders including the ones deeper than the root level, you’ll need to add a line “FOO".
The second component can have zero length, which means that presence of a delimiter character in a filter also forces the filter to be applied to the root sync folder. For example:
will force Sync to ignore a “FOO” folder only in the root sync directory.
Important: on UNIX-based systems use "/" as a path separator.
With the above mentioned ignore lines, the following folder structure will behave this way
\ABC //wil be synced
CDE F //will not be synced, ignored by ABC\CDE F
\123 //will be synced
ABC //will be synced
CDE //will be synced
Filename.pdf //will not be synced, ignored by *.pdf
\FOO //will not be synced, ignored by FOO\*
QWER //will not be synced
DelimitersWhen composing a filter consisting of 2 or more components, note that path delimiters are OS-dependent and not universal. So please do not forget to use “/“ for Mac and unix-based OSes, while for Windows OSes use “\”.
Note: the IgnoreList is applied to the folder where it is contained and its subfolders. It will not work with the files that have already been synced.
Timings and delaysOnce Sync has scanned and indexed the directory tree of a sync folder, all the structural info is going to be stored in its database and always passed to other peers (until you disconnect the sync folder).
It means that if you create or edit your IgnoreList file after the directory was added to Sync, the folder structure will always be fully synced, however, actual files / folders added to the ignore list will not be passed to other peers.
Sync re-reads IgnoreList every time it is changed or (if system notifications are not coming for some reason) every folder_rescan_interval. We recommend to restart Sync if you want to apply changes in the IgnoreList immediately.
