## FAQ
|
||||
|
||||
**When a file is moved to another directory is it still being watched?**
|
||||
|
||||
No (it shouldn't be, unless you are watching where it was moved to).
|
||||
|
||||
**When I watch a directory, are all subdirectories watched as well?**
|
||||
|
||||
No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
|
||||
|
||||
**Do I have to watch the Error and Event channels in a separate goroutine?**
|
||||
|
||||
As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
|
||||
|
||||
**Why am I receiving multiple events for the same file on OS X?**
|
||||
|
||||
Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
|
||||
|
||||
**How many files can be watched at once?**
|
||||
|
||||
There are OS-specific limits as to how many watches can be created:
|
||||
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
|
||||
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
