Question

I have a gray Checkbox or ‘vee’ icon next to a XSL file.
It is identical to the usual ‘green vee’ that appears next to versioned files.

What do it mean?

Answer 1

From the TortoiseSVN help:

If you have set the svn:needs-lock
property on a file, Subversion makes
that file read-only until you get a
lock on that file. Such files have
this overlay to indicate that you have
to get a lock first before you can
edit that file.
