The recent GExperts version created a lot of files (3.500) in my user profile under
AppData\Roaming\GExperts\RAD Studio 10.3\UsesExpertCache\
Not sure if there is a cleanup problem. But in any case such cache files should be placed under AppData\Local\, becuase it makes Roaming profiles slow.
Diff:
It's not a cleanup problem but works as designed. But you are right, it should not use the roaming profile but the local one.
If it is a problem for you: You can reduce the number of files by turning off the "Parse all units, not just the favorites" in the Uses Clause Manager options.
fixed in revision #2554. The cache can now be disabled and by default is stored in AppData\Local. It can also be configured to be placed somewhere else.
